Description
The BTS50060-1EGA is a single channel high-side power switch in PG-DSO-12-16 package providing embedded
protective functions including ReverSaveTM and Infineon® INTELLIGENT LATCH.
The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on
Smart power chip on chip technology.
The BTS50060-1EGA has ground referenced CMOS compatible inputs.
ReverSaveTM is a protection feature that causes the power transistor to switch on in case of reverse polarity. As
a result, the power dissipation is reduced.
Infineon® INTELLIGENT LATCH ensures a latched switch-off and reporting in case of fault condition.
The Infineon® ENHANCED SENSE pin IS provides a sophisticated diagnostic feedback signal including current
sense functionality, open load in ON-state (via sense signal) and open load and short to battery in OFF-state.
Diagnostic reporting can be enabled and disabled by the DEN-Pin in ON-state and OFF-state. In OFF-state, open
load detection can also be disabled by the DEN-Pin to optimize stand-by current.

The power stage is built by a N-channel vertical power MOSFET (DMOS) with charge pump.
5.1
Input Circuit
Figure 5 shows the input circuit of the BTS50060-1EGA. The input resistor to ground ensures that the input signal
is low in case of open input pin. The zener diode protects the input circuit against ESD pulses.

Output On-State Resistance
The on-state resistance RDS(ON) depends on the supply voltage Vbb and the junction temperature Tj. Figure 6
shows these dependencies for the typical on-state resistance. The on-state resistance in reverse polarity mode is

Output Clamp
To prevent destruction of the device, there is a voltage clamp mechanism implemented that keeps the voltage drop
across the device at a certain level. At nominal battery voltage the output is clamped to VOUT(CL). At over voltages
the output is clamped to VDS(CL). See Figure 9 and Figure 10 for details. The maximum allowed load inductance
is limited.

While de-energizing inductive loads, energy has to be dissipated in the BTS50060-1EGA. This energy can be
calculated by the following equation:

The energy, which is converted into heat, is limited by the thermal design of the component. See Figure 11 for the

Inverse Operation Capability
The BTS50060-1EGA can be operated in inverse load current condition (+VOUT > +Vbb). The device can not block
the current flow during inverse mode.
In ON condition a voltage drop across the activated channel of

Undervoltage shutdown and restart
The BTS50060-1EGA is supplied by Vbb. The internal logic permanently monitors the supply voltage Vbb. In the
event that the supply voltage drops below the under voltage shutdown threshold Vbb(u), the BTS50060-1EGA will
switch off. If the supply voltage reaches nominal operating voltage range Vbb(ext), the BTS50060-1EGA will switch
on after a delay tdelay(UV), assuming VIN=High. Protective latch is reset by undervoltage shutdown.

Protection Functions

Protection Functions
The BTS50060-1EGA provides embedded protective functions. Integrated protection functions are designed to
prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as
“outside” normal operating range. Protection functions are neither designed for continuous nor repetitive
operation.
6.1
Short Circuit Protection
The internal logic permanently monitors the load current IL. In the event the load current exceeds the short circuit
shutdown threshold (IL>IL(SC)), the device will switch off immediately. Any protective switch off latches the output.
Please refer to Figure 14 for details. The protective switch off remains latched until the fault is acknowledged and
reset by a falling edge at the DEN pin. See also Chapter 6.4.

Shutdown by short circuit current detection
Before switching on, the device is measuring the battery voltage Vbb(0). In case Vbb(0) is above Vbb(SCT), the short
circuit current threshold IL(SC)high is reduced to a lower level IL(SC)low.
Note: In case of a short circuit between OUT and ground, an impedance between Vbat and Vbb pin of the device
(see Figure 15) may cause the device’s supply voltage to drop below Vbb(u) before short circuit shutdown
threshold is reached. In that case, the device will detect an undervoltage condition and behave as described
in Chapter 5.7.
6.2
Short Circuit Impedance
The capability to handle single short circuit events depends on the battery voltage as well as on the primary and
secondary short impedance. Figure 15 outlines allowable combinations for a single short circuit event of
maximum, secondary inductance for given secondary resistance.

Infineon® INTELLIGENT LATCH - fault acknowledge and latch reset
The BTS50060-1EGA provides Infineon® INTELLIGENT LATCH to avoid permanent resetting of a protective,
latched switch off in PWM applications. To reset a latched protective switch off the fault has to be acknowledged
by a falling edge at the DEN pin. For a reset signal it’s recommended to set the DEN signal to HIGH for 20µs before
setting DEN to LOW for 20µs.
Please refer to Figure for details.

The device can not block a current flow in reverse battery condition. In order to minimize power dissipation, the

6.8
Loss of Load Protection, Loss of Vbb Protection
In case of loss of load with charged primary inductances the maximum supply voltage has to be limited. It is
recommended to use a Z-diode, a varistor (VZa < 42 V) or Vbb clamping power switches with connected loads in
parallel.
In case of loss of Vbb connection with charged inductive loads, a current path with load current capability has to
be provided, to demagnetize the charged inductances. It is recommended to use a diode, a Z-diode or a varistor
(VZb < 16 V, VZL+VD < 16 V, ).
For higher clamp voltages currents through all pins have to be limited according to the maximum ratings. Please
refer to Figure 19 for details.

For diagnosis purposes, the BTS50060-1EGA provides an Infineon® ENHANCED SENSE signal at the pin IS.
7.1
Diagnosis Enable
In ON-State, diagnosis is allways enabled. Providing a low signal at the DEN pin will disable the reporting. In OFFstate, both, reporting and diagnosis can be disabled by a low signal at DEN pin. The pin IS will be set to tri-state
mode when a low signal is provided at the DEN pin. A high signal at the DEN pin enables the reporting and the
open load and short to battery diagnosis during OFF mode. A falling edge at the DEN resets a preceding latched
output and reporting condition. Please see Figure 20 and Table 1 for details.

Diagnosis during ON
During normal operation, an enabled IS pin provides a sense current, which is proportional to the load current as
long as Vb,IS>5V and as long as IIS*RIS<VZ,IS. The ratio of the output current is defined as kILIS=IL/IIS. During switchon sense current is provided after a sense settling time tsIS(ON). During inverse operation and switch-off no current
is provided.
The output sense current is limited to IIS,lim. Please refer to Figure 21 for details.

During normal operation a disabled IS pin provides no current.
In case of shorted load to battery, open load or inverse operation an enabled IS pin provides a defined fault current
IIS(fault). See Figure 25 for details.

Diagnosis Disable
In order to achieve minimum standby current, the IN pin and the DEN pin have to be low level. A possible
preceding fault condition and reporting has to be reset by a falling edge at the pin DEN. See also Chapter 6.4 for
details.

Handling of NC pins: It is recommended to connect all NC pins on a defined potential. E.g. pin 7 and pin 12
could be connected to OUT potential, while pin 5 and 6 could be connected to OUT or DEN.
EMC filter cap between Vbb and GND: It is recommended to place the filter cap as close as possible to the
device to minimize the inductance of the loop.
The resistors connecting µC and IN-pin as well as µC and DEN-pin are recommended to protect the µC inputs
against fast electrical transients.
Ground shift: It is recommended to avoid a ground shift between µC ground and device pin GND of more than
0.3V during normal operation.
