Description
The VND7140AJ-E is a double channel high-side driver manufactured using ST proprietary VIPower® technology and housed in PowerSSO-16 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, 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 VCC and 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. Max transient supply voltage VCC 40 V Operating voltage range VCC 4 to 28 V Typ. on-state resistance (per Ch) RON 140 mΩ Current limitation (typ) ILIMH 12 A Standby current (max) ISTBY 0.5 µA
