The VN5E050ASO-E is a single channel high-side driver with analog current sense for automotive applications. It has various features, including active management of inrush current by power limitation, very low standby current, 3.0V CMOS compatible inputs, optimized electromagnetic emissions, very low electromagnetic susceptibility, compliance with European directive 2002/95/EC, very low current sense leakage, and AEC-Q100 qualification.
The VN5E050ASO-E is a single channel high-side driver manufactured using ST proprietary ViPower® MO-5 technology. It is housed in the SO-16L package and designed to drive 12 V automotive grounded loads while providing protection and diagnostics.
The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto-restart, and overvoltage active clamp. A dedicated analog current sense pin provides enhanced diagnostic functions including fast detection of overload and short-circuit to ground.
