Description
The VNQ830PEP-E is a monolithic device made using| STMicroelectronics VIPowerTM M0-3 Technology. The VNQ830PEP-E is intended for driving any type of multiple 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 detects the open load condition in both the on and off-state. In the off-state the device detects if the output is shorted to VCC. The device automatically turns off in the case where the ground pin becomes disconnected.

Electrical specifications
Absolute maximum ratings
Stressing the device above the rating listed in the "Absolute maximum ratings" table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality document. Table 3.

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: a resistor in the ground line (RGND only)
This can be used with any type of load. The following show how to dimension the RGND resistor: 1. 2. RGND 600mV / 2 (IS(on)max) 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.
16/27
Doc ID 10871 Rev 7
VNQ830PEP-E
Application information
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 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 requires the use of a large resistor, or several devices have to share the same resistor, then ST suggests using solution 2 below.
3.1.2
Solution 2: a diode (DGND) in the ground line
A resistor (RGND = 1k) should be inserted in parallel to DGND if the device will be driving an inductive load. This small signal diode can be safely shared amongst several different HSD. Also in this case, the presence of the ground network will produce a shift (j600mV) in the input threshold and the status output values if the microprocessor ground is not common with the 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.
3.2
Load dump protection
Dld is necessary (voltage transient suppressor) if the load dump peak voltage exceeds the VCC maximum DC rating. The same applies if the device is subject to transients on the VCC line that are greater than those shown in the ISO T/R 7637/1 table.
3.3
MCU I/O protection
If a ground protection network is used and negative transients 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 C I/O pins from latching up. The value of these resistors is a compromise between the leakage current of C and the current required by the HSD I/Os (Input levels compatibility) with the latch-up limit of C I/Os: - VCCpeak / Ilatchup Rprot (VOHC - VIH - VGND) / IIHmax
Example
For the following conditions: VCCpeak = - 100V Ilatchup 20mA VOHC 4.5V 5k Rprot 65k. Recommended values are: Rprot = 10k

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.
