The device is DS10831 - Rev 4 - July 2018 www.st.com For further information contact your local STMicroelectronics sales office.VN7020AJ designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS- compatible interface, providing protection and diagnostics. The device integrates advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown with configurable latch-off. A FaultRST pin unlatches the output in case of fault or disables the latch-off functionality. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions including high precision proportional load current sense, supply voltage feedback and chip temperature sense, in addition to the detection of overload and short circuit to ground, short to V and OFF-state open-load. CC A sense enable pin allows OFF-state diagnosis to be disabled during the module low- power mode as well as external sense resistor sharing among similar devices. DS10831 - Rev 4 page 2/45
