Power Stage
The power stage is built by a N-channel power MOSFET (DMOS) with charge pump.
5.1.1
Output ON-State Resistance
The ON-state resistance RDS(ON) depends on the supply voltage as well as the junction temperature TJ. Page 42
shows the dependencies in terms of temperature and supply voltage, for the typical ON-state resistance. The
behavior in reverse polarity is described in Chapter 5.3.5.
A HIGH signal (see Chapter 5.2) at the input pin causes the power DMOS to switch ON with a dedicated slope,
which is optimized in terms of EMC emission.
5.1.2
Switching Resistive Loads
Figure 8 shows the typical timing when switching a resistive load. The power stage has a defined switching
behavior. Defined slew rates results in lowest EMC emission at minimum switching losses.

When switching OFF inductive loads with high side switches, the voltage VOUT drops below ground potential,
because the inductance intends to continue driving the current. To prevent the destruction of the device due
to high voltages, there is a Infineon® SMART CLAMPING mechanism implemented that keeps negative output
voltage to a certain level (VS - VDS(CL)). Please refer to Figure 9 and Figure 10 for details. Nevertheless, the
maximum allowed load inductance remains limited.

The energy, which is converted into heat, is limited by the thermal design of the component. See Figure 5 for
the maximum allowed energy dissipation as function of the load current.
5.1.4
Switching Active Loads
When switching generative or electronic loads such as motors or secondary ECUs which have the ability to
feed back voltage disturbances to the OUT pins, special attention is required about the resulting absolute and
dynamic voltage VDS between VS pin and OUT pins.
To maintain device functionality it is required to limit the maximum positive or negative slew rate of
VDS = VS - VOUT below |dVDS/dt| (parameter P_4.2.7) .
In case the device operates at low battery voltage (VS < 8 V) where the load feeds back a positive output voltage
reaching almost VS potential (0 < VDS < 1 V), it has to be ensured that for each activation (turn-on event), where
the device is commanded on by applying VIN(H) at IN pin, a maximum positive or negative slew rate of VDS below
|dVDS/dt| (parameter P_4.2.8) will not be exceeded until tON(DELAY) has expired (maxium 150 µs after turn-on
command).
For loads that generate steady or dynamic voltage at the OUT pins which is higher than voltage at VS pin
please consider Chapter 5.1.5.

Inverse Current Capability
In case of inverse current, meaning a voltage VOUT(INV) at the output higher than the supply voltage VS, a current
IL(INV) will flow from output to VS pin via the body diode of the power transistor (please refer to Figure 11). In
case the IN pin is HIGH, the power DMOS is already activated and will continue to remain in ON state during
the inverse event. In case, the input goes from “L” to “H”, the DMOS will be activated even during an inverse
event. Under inverse condition, the device is not overtemperature / overload protected. During inverse mode
at ON the sense pin will provide a leakage current of less or equal to IIS0. Due to the limited speed of INV
comparator, the inverse duration needs to be limited.

PWM Switching
The switching losses during this operation should be properly considered (see following equation):
PTOTAL = (switching_ON_energy + switching_OFF_energy + IL2 × RDS(ON) × tDC) / period
PWM switching application slightly above tIN(RESETDELAY) parameter (see Figure 25) with calculated power
dissipation PTOTAL > PTOT parameter limit causes an effective increase in TJ(TRIP) parameter.
In the event of a fault condition it has to be ensured, that the PWM frequency will not exceed a maximum retry
frequency of fFAULT (parameter P_4.1.9). With this measure the short circuit robustness nRSC1 (parameter
P_4.1.4) can be utilized. Operation at nominal PWM frequency can only be restored, once the fault condition
is overcome.

Advanced switch-off behavior
In order to reduce device stress when switching OFF critical loads and/or critical load conditions, the device
provides an advanced switch off functionality which results in a typically ten times faster switch off behavior.
This fast switch off functionality is triggered by one the following conditions:
•
The device is commanded off by applying VIN(L) at the IN pin. During the switch OFF operation the OUT pins’
voltage in respect to GND pin drops to typically -3 V or below (typically VOUT – VGND ≤ -3 V).
•
The device is commanded on or is already in on-state. The device then detects a short circuit condition
(IL ≥ ICL(0)) and initiates a protective switch off. Please refer to Chapter 5.3.6.1 and Chapter 5.3.6.2 for
details.

Input Circuitry
The input circuitry is compatible with 3.3 V and 5 V microcontrollers or can be directly driven by VS. The

OFF. Figure 14 shows the electrical equivalent input circuitry.

Input Pin Voltage
The IN uses a comparator with hysteresis. The switching ON / OFF takes place in a defined region, set by the
threshold VIN(L) Max and VIN(H) Min. The exact value where ON and OFF take place depends on the process, as well
as the temperature. To avoid cross talk and parasitic turn ON and OFF, an hysteresis is implemented. This
ensures immunity to noise.
5.3
Protection Functions
The device provides embedded protective functions. Integrated protection functions are designed to prevent
the destruction of the IC from fault conditions described in the data sheet. Fault conditions are considered as
“outside” normal operating range. Protection functions are designed neither for continuous nor for repetitive
operation.

Loss of Ground Protection
In case of loss of module or device ground, where the load remains connected to ground, the device protects
itself by automatically turning OFF (when it was previously ON) or remains OFF, regardless of the voltage
applied at IN pin. It is recommended to use input resistors between the microcontroller and the
BTS50015-1TAD to ensure switching OFF of channel. In case of loss of module or device ground, a current
(IOUT(GND)) can flow out of the DMOS. Figure 16 sketches the situation.

Protection during Loss of Load or Loss of VS Condition
In case of loss of load with charged primary inductances the supply voltage transient has to be limited. It is
recommended to use a Zener diode, a varistor or VS clamping power switches with connected loads in parallel.
The voltage must be limited according to the minimum value of the parameter 6.1.33 indicated in Table 6.

Functional Description
In case of loss of VS connection with charged inductive loads, a current path with sufficient load current
capability has to be provided, to demagnetize the charged inductances. It is recommended to protect the
device using a Zener diode together with a diode (VZ1 + VD1 < 16 V), with path (A) or path (B) as shown in
Figure 17.
For a proper restart of the device after loss of VS, the input voltage must be delayed compared to the supply
voltage ramp up. This can be realized by a capacitor between IN and GND (see Figure 30).
For higher clamp voltages, currents through all pins have to be limited according to the maximum ratings.
Please see Figure 17 and Figure 18 for details.

Undervoltage Behavior
If the device is already ON and the power supply decreases but remains above the VS(UV), no effect is observed
and the device keeps on working normally (case 1, Figure 19)
If the power supply falls below the VS(UV) but remains above the VS(EXT,DYN), the device turns off, but it turns
automatically on again when the power supply goes above Min. VS(EXT) (case 2, Figure 19).
In case the power supply becomes lower than VS(EXT,DYN), the device turns off and can be switched on again only
after a reset signal at the IN pin, provided that the power supply is higher than Min. VS(EXT) (case 3, Figure 19).

BTS50015-1TAD
Smart High-Side Power Switch
Functional Description
5.3.4
Overvoltage Protection
In case VS(SC)_max < VS < VDS(CL), the device will switch ON/OFF normally as in the nominal voltage range.
Parameters may deviate from the specified limits and lifetime is reduced. This specially impacts the short
circuit robustness, as well as the maximum energy EAS and EAR the device can handle.
The BTS50015-1TAD provides Infineon® SMART CLAMPING functionality, which suppresses excessive transient
overvoltage by actively clamping the overvoltage across the power stage and the load. This is achieved by
controlling the clamp voltage VDS(CL) depending on the junction temperature TJ and the load current IL (see
Figure 20 for details).

Reverse Polarity Protection
In case of reverse polarity, the intrinsic body diode of the power DMOS causes power dissipation. To limit the
risk of overtemperature, the device provides Infineon® ReverSave™ functionality. The power in this intrinsic
body diode is limited by turning the DMOS ON. The DMOS resistance is then equal to RDS(REV).
Additionally, the current into the logic has to be limited. The device includes a RVS resistor which limits the
current in the diodes. To avoid overcurrent in the RVS resistor, it is nevertheless recommended to use a RIN
resistor. Please refer to maximum current described in Chapter 4.1.
Figure 21 shows a typical application.
RIS is used to limit the current in the sense transistor, which behaves as a diode.
The recommended typical value for RIN is 4.7 kΩ and for RIS 1 kΩ.

Overload Protection
In case of overload, high inrush current or short circuit to ground, the BTS50015-1TAD offers several protection
mechanisms. Any protective switch OFF latches the output. To restart the device, it is necessary to set
IN = LOW for t > tIN(RESETDELAY). This behavior is known as latch behavior. Figure 25 gives a sketch of the
situation.
5.3.6.1
Activation of the Switch into Short Circuit (Short Circuit Type 1)
When the switch is activated into short circuit, the current will raise until reaching the ICL(0) value. After tOFF(TRIP),
the device will turn OFF and latches until the IN pin is set to low for t > tIN(RESETDELAY). Under certain supply
undervoltage shutdown conditions (for example VS < VS(EXT,DYN)) the latched fault may be reset. For overload
(short circuit or overtemperature), the maximum retry cycle (ffault) under fault condition must be considered.
5.3.6.2
Short Circuit Appearance when the Device is already ON (Short Circuit Type 2)
When the device is in ON state and a short circuit to ground appears at the output (SC2) with an overcurrent
higher than ICL(0) for a time longer than tOFF(TRIP), the device automatically turns OFF and latches until the IN pin
is set to low for t > tIN(RESETDELAY). Under certain supply undervoltage shutdown conditions (for example
VS < VS(EXT,DYN)) the latched fault may be reset.
5.3.6.3
Influence of the battery wire inductance
The wire between the battery and the VS pin includes typically some parasitic inductance.
When the device switches off due to a short circuit event, the energy stored in the line inductance together
with the capacitance (either the capacitor placed at VS pin or the internal capacitance between drain and
source) could trigger an oscillatory behavior on the supply line at short circuit turn-off (see Figure 22), whose
frequency depends on the inductance and capacitance values.

Oscillations at VS pin
The oscillations can pull the VS pin voltage to GND or even below. In some cases this behaviour may cause the
device to reset the fault generated by the overcurrent event. As consequence the device may switch on again,
as soon as the VS reaches an adequate value. The short circuit condition will be detected again and then the
device will switch off. Short circuits and resets of the fault condition may repeatedly occur (see Figure 23).

Functional Description
Potential solutions to dampen such oscillation and to achieve an effectively latching overcurrent protection
is a RC snubber network, which needs to be connected between the VS pin and device or module GND.
Figure 24 shows RC snubber circuits for each GND connection. For detailed information see Chapter 7.

The design of the most suitable RC snubber network is beyond the scope of this chapter. Nevertheless the
recommendation given in Chapter 7 contribute to effectively dampen the oscillation for typical line
inductance and CVS.
5.3.7
Temperature Limitation in the Power DMOS
The BTS50015-1TAD incorporates an absolute (TJ(TRIP)) temperature sensor. Activation of the sensor will cause
an overheated channel to switch OFF to prevent destruction. The device restarts when the IN pin is set to low
for t > tIN(RESETDELAY) and the temperature has decreased below TJ(TRIP) - ∆TJ(TRIP). Under certain undervoltage
shutdown conditions (for example below VS(EXT,DYN)) the latched fault might be reset.

The current sense exact signal timing can be found in the Chapter 5.4. It is represented here only for device’s
behavior understanding.
In order to allow the device to detect overtemperature conditions and react effectively, it is recommended to
limit the power dissipation below PTOT (parameter 4.1.15).
5.4
Diagnostic Functions
For diagnosis purposes, the BTS50015-1TAD provides a combination of digital and analog signal at pin IS.
5.4.1
IS Pin
The BTS50015-1TAD provides an enhanced current sense signal called IIS at pin IS. As long as no “hard” failure
mode occurs (short circuit to GND / overcurrent / overtemperature) and the condition VIS ≤ VOUT - 5 V is fulfilled,
a proportional signal to the load current is provided. The complete IS pin and diagnostic mechanism is
described in Figure 26. The accuracy of the sense current depends on temperature and load current. In case
of failure, a fixed IIS(FAULT) is provided. In order to enable the fault current reporting, the condition VS - VOUT > 2 V
must be fulfilled. In order to get the fault current in the specified range, the condition VS - VIS ≥ 5 V must be
fulfilled.

Figure 27 and Figure 28 show the current sense as function of the load current in the power DMOS. Usually, a
pull-down resistor RIS is connected to the current sense pin IS. A typical value is 1 kΩ. The dotted curve
represents the typical sense current, assuming a typical dkILIS factor value. The range between the two solid
curves shows the sense accuracy range that the device is able to provide, at a defined current.

SENSE Signal Variation and Calibration
In some applications, an enhanced accuracy is required around the device nominal current range IL(NOM). To
achieve this accuracy requirement, a calibration on the application is possible. After two point calibration, the
BTS50015-1TAD will have a limited IIS value spread at different load currents and temperature conditions. The
IIS variation can be described with the parameters ∆(dkILIS(cal)) and the ∆IIS0(cal). The blue solid line in Figure 28
is the current sense ratio after the two point calibration at a given temperature. The slope of this line is defined
as follows:
1
dkILIS(cal)
=
IIS(cal)2 − IIS(cal)1
IL(cal)2 − IL(cal)1
(5.6)
Data Sheet

The offset is defined as follows:
IIS0(cal) = IIS(cal)1 −
IL(cal)1
IL(cal)2
= IIS(cal)2 −
dkILIS(cal)
dkILIS(cal)
(5.7)
The bluish area in Figure 28 is the range where the current sense ratio can vary across temperature and load
current after performing the calibration. The accuracy of the load current sensing is improved and, given a
sense current value IIS (measured in the application), the load current can be calculated as follow, using the
absolute value for ∆(dkILIS(cal)) instead of % values:
(
) (
IL = dkILIS(cal) × 1 + ∆(dkILIS(cal)) × IIS − IIS0(cal) − ∆IIS0(cal)
)
(5.8)
where dkILIS(cal) is the current sense ratio measured after two-points calibration (defined in Equation (5.6)),
IIS0(cal) is the current sense offset (calculated after two points calibration, see Equation (5.7)), and ∆IIS0(cal) is the
additional variation of the individual offset over life time and temperature. For a calibration at 25°C ∆IIS0(cal)
varies over temperature and life time for all positive ∆IIS0(cal) within the differences of the temperature
dependent Max. limits. All negative ∆IIS0(cal) vary within the differences of the temperature dependent Min.
limits.
For positive IIS0(cal) values (IIS0(cal) > 0):
Max IIS0 (@TJ = 150°C) − Max IIS0 (@TJ = 25°C) ≤ ∆IIS0(cal) ≤ Max IIS0 (@TJ = -40°C) − Max IIS0 (@TJ = 25°C)
(5.9)
For negative IIS0(cal) values (IIS0(cal) < 0):
Min IIS0 (@TJ = 150°C) − Min IIS0 (@TJ = 25°C) ≥ ∆IIS0(cal) ≥ Min IIS0 (@TJ = -40°C) − Min IIS0 (@TJ = 25°C)
(5.10)
Equation (5.8) actually provides four solutions for load current, considering that ∆(dkILIS(cal)) and ∆IIS0(cal) can
be both positive and negative. The load current IL for any sense current IIS will spread between a minimum IL
value resulting from the combination of lowest ∆(dkILIS(cal)) value and highest ∆IIS0(cal) and a maximum IL value
resulting from the combination of highest ∆(dkILIS(cal)) value and lowest ∆IIS0(cal).

SENSE Signal in Case of Short Circuit to VS
t
In case of a short circuit between OUT and VS, a major part of the load current will flow through the short
circuit. As a result, a lower current compared to the nominal operation will flow through the DMOS of the
BTS50015-1TAD, which can be recognized at the current sense signal.
5.4.3.4
SENSE Signal in Case of Over Load
An over load condition is defined by a current flowing out of the DMOS reaching the current over load ICL or the
junction temperature reaches the thermal shutdown temperature TJ(TRIP). Please refer to Chapter 5.3.6 for
details. In that case, the SENSE signal will be in the range of IIS(FAULT) when the IN pin stays HIGH.
This is a device with latch functionality. The state of the device will remain and the sense signal will remain on
IIS(FAULT) until a reset signal comes from the IN pin. For example, when a thermal shutdown occurs, even when
the over temperature condition has disappeared, the DMOS can only be reactivated when a reset signal is sent
to the IN pin.
