VND5E025BK-E Double channel high-side driver with analog current sense for automotive applications Features Max transient supply voltage VCC 41 V Operating voltage range VCC 4.5 to 28 V Max on-state resistance (per ch.) RON 25 mΩ Current limitation (typ) ILIMH 60 A Off-state supply current IS 2 µA(1) PowerSSO-24 ■ All types of resistive, inductive and capacitive loads and suitable as LED driver 1. Typical value with all loads connected. Description ■ General – Inrush current active management by power limitation – Very low standby current – 3.0V CMOS compatible inputs ■ Diagnostic functions – High current sense precision for wide currents range – Current sense ratio drift for single point calibration – Current sense disable – Overload and short to ground (power limitation) indication – Thermal shutdown indication ■ Protections – Undervoltage shutdown – Overvoltage clamp – Load current limitation – Self limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Overtemperature shutdown with auto restart (thermal shutdown) – Reverse battery protected – Electrostatic discharge protection Applications ■ The VND5E025BK-E is a double channel highside driver manufactured in the ST proprietary VIPower™ M0-5 technology and housed in the tiny PowerSSO-24 package. The VND5E025BK-E is designed to drive 12V automotive grounded loads delivering protection, diagnostics and easy 3V and 5V CMOS compatible interface with any microcontroller. The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto restart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide Enhanced diagnostic functions including fast detection of overload and short circuit to ground through power limitation indication and overtemperature indication. An improved current sense circuitry and the introduction of a new current sense ratio drift, dK/K(tot), allow the "single-point" calibration and ensure a very high accuracy in case of "doublepoint" calibration. The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to allow sharing of the external sense resistor with other similar devices.

Application schematic +5V VCC Rprot CS_DIS Dld ΜCU Rprot INPUT OUTPUT Rprot CURRENT SENSE GND RSENSE VGND CEXT RGND DGND Note: Channel 2 has the same internal circuit as channel 1. 3.1 GND protection network against reverse battery This section provides two solutions for implementing a ground protection network against reverse battery. 3.1.1 Solution 1: resistor in the ground line (RGND only) This can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1. RGND ≤ 600 mV / (IS(on)max) 2. RGND ≥ (−VCC) / (-IGND) where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. Power dissipation in RGND (when VCC<0: during reverse battery situations) is: PD= (-VCC)2/RGND This resistor can be shared amongst several different HSDs. Please note that the value of this resistor should be calculated with formula (1) where IS(on)max becomes the sum of the maximum On-state currents of the different devices. Please note that if the microprocessor ground is not shared by the device ground then the RGND will produce a shift (IS(on)max * RGND) in the input thresholds and the status output 22/34 Doc ID 16273 Rev 7 VND5E025BK-E Application information values. This shift will vary depending on how many devices are On in the case of several high-side drivers sharing the same RGND. If the calculated power dissipation leads to a large resistor or several devices have to share the same resistor then ST suggests to utilize Solution 2 (see below). 3.1.2 Solution 2: diode (DGND) in the ground line A resistor (RGND=1 kΩ) should be inserted in parallel to DGND if the device drives an inductive load. This small signal diode can be safely shared amongst several different HSDs. Also in this case, the presence of the ground network will produce a shift (≈600mV) in the input threshold and in the status output values if the microprocessor ground is not common to the device ground. This shift will not vary if more than one HSD shares the same diode/resistor network. 3.2 Load dump protection Dld is necessary (voltage transient suppressor) if the load dump peak voltage exceeds the VCC max DC rating. The same applies if the device is subject to transients on the VCC line that are greater than the ones shown in the ISO 7637-2: 2004(E) table. 3.3 MCU I/Os protection If a ground protection network is used and negative transient are present on the VCC line, the control pins will be pulled negative. ST suggests to insert a resistor (Rprot) in line to prevent the MCU I/Os pins to latch-up. The value of these resistors is a compromise between the leakage current of MCU and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of MCU I/Os: -VCCpeak/Ilatchup ≤ Rprot ≤ (VOHμC-VIH-VGND) / IIHmax Calculation example: For VCCpeak = - 100 V and Ilatchup ≥ 20 mA; VOHµC ≥ 4.5 V 5 kΩ ≤ Rprot ≤ 180 kΩ Recommended values: Rprot =10 kΩ, CEXT=10 nF. Doc ID 16273 Rev 7 23/34 Application information 3.4 VND5E025BK-E Current sense and diagnostic The current sense pin performs a double function (see Figure 30: Current sense and diagnostic): ● Current mirror of the load current in normal operation, delivering a current proportional to the load one according to a known ratio KX. The current ISENSE can be easily converted to a voltage VSENSE by means of an external resistor RSENSE. Linearity between IOUT and VSENSE is ensured up to 5V minimum (see parameter VSENSE in Table 9: Current sense (8V < VCC < 18V)). The current sense accuracy depends on the output current (refer to current sense electrical characteristics Table 9: Current sense (8V < VCC < 18V)). ● Diagnostic flag in fault conditions, delivering a fixed voltage VSENSEH up to a maximum current ISENSEH in case of the following fault conditions (refer to Truth table): – Power limitation activation – Overtemperature A logic level high on CS_DIS pin sets at the same time all the current sense pins of the device in a high impedance state, thus disabling the current monitoring and diagnostic detection. This feature allows multiplexing of the microcontroller analog inputs by sharing of sense resistance and ADC line among different devices. Figure 30.
