describe
The device is a single channel high-end drive, using ST's proprietary vipower ® M0-7 technology and installed in powerso-16 package. The device is designed to drive a 12V vehicle grounding load through a 3V and 5vcmos compatible interface to provide protection and diagnosis.
The equipment integrates advanced protection functions, such as load current limit, power limit of overload active management, over temperature shutdown and configurable lockout shutdown.
The faultrst pin unlocks the output or disables the latch off function when a fault occurs.
The dedicated multi-functional multi-channel analog output pins provide complex diagnostic functions, including high-precision proportional load current, power supply voltage feedback and chip temperature sensing, as well as detecting overload and short circuit to ground, short circuit to VCC and disconnected load.
The sense enable pin allows the off state diagnosis to be disabled in the low power mode of the module and the sharing of external sense resistance between similar devices.
