VN750PS-E High-side driver Features Type RDS(on) IOUT VCC VN750PS-E 60 m 6A 36 V ECOPACK(R) : lead free and RoHS compliant Automotive Grade: compliance with AEC guidelines CMOS compatible input On-state open-load detection Off-state open-load detection Shorted load protection Undervoltage and overvoltage shutdown Protection against loss of ground Very low standby current Reverse battery protection SO-8 Description The VN750PS-E is a monolithic device designed in STMicroelectronicsTM VIPowerTM M0-3 Technology intended for driving any kind of load with one side connected to ground. 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 help protect the device against overload. The device detects open load condition in on and off-state. Output shorted to VCC is detected in the off-state. Device automatically turns off in case of ground pin disconnection. Table 1.

Application schematic +5V +5V VCC Rprot STATUS Dld C Rprot INPUT OUTPUT GND VGND 2.5 RGND DGND GND protection network against reverse battery 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 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 below). 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 will produce a shift (600 mV) in the input threshold and in the status output values if the microprocessor ground is not common to the 16/27 Doc ID 16782 Rev 3 VN750PS-E Electrical specifications device ground. This shift will 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. 2.6 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. 2.7 Microcontroller 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 microcontroller I/O 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. 2.8 Open-load detection in off-state Off-state open-load detection requires an external pull-up resistor (RPU) connected between output pin and a positive supply voltage (VPU) like the +5V line used to supply the microprocessor. The external resistor has to be selected according to the following requirements: 1. no false open-load indication when load is connected: in this case we have to avoid VOUT to be higher than VOlmin; this results in the following condition VOUT = (VPU / (RL + RPU))RL < VOlmin. 2. no misdetection when load is disconnected: in this case the VOUT has to be higher than VOLmax; this results in the following condition RPU < (VPU - VOLmax) / IL(off2). Because Is(OFF) may significantly increase if Vout is pulled high (up to several mA), the pullup resistor RPU should be connected to a supply that is switched off when the module is in standby. The values of VOLmin, VOLmax and IL(off2) are available in the electrical characteristics section. Doc ID 16782 Rev 3 17/27 Electrical specifications VN750PS-E Figure 25.
