| VN751S High side driver Features Type VN751S RDS(on) 60 m Iout 2.5 A VCC 36 V SO-8 CMOS compatible input Thermal shutdown Shorted load protection Undervoltage and overvoltage shutdown Protection against loss of ground Very low stand-by current Compliance to 61000-4-4 IEC test up to 4 kV Description The VN751S is a monolithic device designed in STMicroelectronics VIPower 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. Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. Device automatically turns off in case of ground pin disconnection. This device is especially suitable for industrial applications in conformity with IEC 61131-2 programmable controllers international standard. Figure 1.

Application schematic Application schematic VN751S 10/17 VN751S Reverse polarity protection 7 Reverse polarity protection A schematic solution to protect the IC against a reverse polarity condition is proposed. This schematic is effective with any type of load connected to the outputs of the IC. The RGND resistor value can be selected according to the following conditions to be met: 1. 2. RGND 600 mV / (IS in ON state 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. The power dissipation associated to RGNG during reverse polarity condition is: PD = (-VCC)2/RGND This resistor can be shared by several different ICs. In such case IS value on formula (1) is the sum of the maximum ON-state currents of the different devices. Please note that if the microprocessor ground and the device ground are separated then the voltage drop across the RGND (given by IS in ON state max * RGND) produce a difference between the generated input level and the IC input signal level. This voltage drop will vary depending on how many devices are ON in the case of several high side switches sharing the same RGND. Figure 9.
