Description
AI
The device is a single channel high-side driver manufactured using ST proprietary VIPower®M0-7 technology and housed in PowerSSO-36 package. The device is 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 and overload management by ΔTJand over-temperature shut-down with latch-off.
A toggling on the INPUT pin unlatches the output in case of fault.
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 VCCand OFF-state open-load.
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.
A R_mode pin allows to switch low respectively high RDSonoperating mode, so to adapt current sense precision and current limitation accordingly to the selected load.
