VN920SP-E High-side driver Features Type RDS(on) IOUT VCC VN920SP-E 15 m 30 A 36 V ECOPACK(R): lead free and RoHS compliant Automotive Grade: compliance with AEC guidelines Very low standby current CMOS compatible input Proportional load current sense Current sense disable Thermal shutdown protection and diagnosis Undervoltage shutdown Overvoltage clamp Load current limitation Description The VN920SP-E is a monolithic device designed in STMicroelectronicsTM VIPowerTM M0-3 technology. The VN920SP-E is intended for driving any type of load with one side connected to ground. The active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). Active current limitation combined with thermal shutdown and automatic restart protects the device against overload. The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns-off in the case where the ground pin becomes disconnected. Table 1.

To ensure long term reliability under heavy over-load or short circuit conditions, protection and related diagnostic signals must be used together with a proper software strategy.

Application schematic +5V VCC Rprot INPUT Dld C Rprot OUTPUT CURRENT SENSE RSENSE GND VGND RGND DGND 3.1 GND 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's 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 produces a shift (IS(on)max * RGND) in the input thresholds and the status output values. This shift varies 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 Section 3.1.2). Doc ID 10896 Rev 3 17/27 Application information 3.1.2 VN920SP-E Solution 2: diode (DGND) in the ground line A resistor (RGND = 1 k) 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 produces 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 does not vary if more than one HSD shares the same diode/resistor network. Series resistor in INPUT and STATUS lines are also required to prevent that, during battery voltage transient, the current exceeds the absolute maximum rating. Safest configuration for unused INPUT and STATUS pin is to leave them unconnected, while unused SENSE pin has to be connected to ground pin. 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 Table 12. 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 is pulled negative. ST suggests to insert a resistor (Rprot) in line to prevent the microcontroller I/Os pins to latch-up. The value of these resistors is a compromise between the leakage current of microcontroller and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of microcontroller I/Os. -VCCpeak/Ilatchup Rprot (VOHC-VIH-VGND) / IIHmax Calculation example: For VCCpeak = -100 V and Ilatchup 20 mA; VOHC 4.5 V 5 k Rprot 65 k. Recommended values: Rprot = 10 k. 18/27 Doc ID 10896 Rev 3 VN920SP-E 3.4 Application information PowerSO-10 maximum demagnetization energy (VCC = 13.5 V) Figure 20.
