The VN5E010AH is a single-channel high-side driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny HPAK package. The VN5E010AH is designed to drive 12 V automotive grounded loads delivering protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any microcontroller.
The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with autorestart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide ehnanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to Vcc diagnosis and ON- and OFF-state open-load detection.
The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to allow sharing of the external sense resistor with other similar devices.
Inrush current active management by power limitation Very low standby current 3 V CMOS compatible inputs Optimized electromagnetic emissions Very low electromagnetic susceptibility In compliance with the 2002/95/EC european directive Very low current sense leakage
Undervoltage shutdown Overvoltage clamp Load current limitation Self limiting of fast thermal transients Protection against loss of ground and loss of VCC Overtemperature shut down with autorestart (thermal shutdown) Reverse battery protection with self switch on of the Power MOSFET Electrostatic discharge protection
