5 / 46 page VN7020AJ Block diagram and pin description 1 Block diagram and pin description Figure 1: Block diagram Table 1: Pin functions Name Function VCC Battery connection. OUTPUT Power outputs. All the pins must be connected together. GND Ground connection. Must be reverse battery protected by an external diode / resistor network. INPUT Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V CMOS outputs. It controls output switch state. MultiSense Multiplexed analog sense output pin; it delivers a current proportional to the selected diagnostic: load current, supply voltage or chip temperature. SEn Active high compatible with 3 V and 5 V CMOS outputs pin; it enables the MultiSense diagnostic pin. SEL0,1 Active high compatible with 3 V and 5 V CMOS outputs pin; they address the MultiSense multiplexer. FaultRST Active low compatible with 3 V and 5 V CMOS outputs pin; it unlatches the output in case of fault; If kept low, sets the outputs in auto-restart. mode Control & Diagnostic VCC VON Limitation Current Limitation VCC – OUT Clamp Internal supply OUTPUT Current Sense GND Undervoltage shut-down VCC – GND Clamp Fault T Short to VCC Open-Load in OFF Overtemperature Power Limitation T VSENSEH INPUT SEL0 SEL1 SEn MultiSense FaultRST VCC Gate Driver GAPGCFT00328 DocID027402 Rev 2 5/46 |
