Description The VN5E050J-E is a single channel high-side driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny PowerSSO-12 package. Diagnostic functions – Open Drain status output – On-state open load detection – Off-state open load detection – Output short to VCC detection – Overload and short to ground (power limitation) indication – Thermal shut-down indication The VN5E050J-E is designed to drive automotive grounded loads delivering protection, diagnostics and easy 3V and 5V CMOS-compatible interface with any microcontroller. Protections – Undervoltage shut-down – Overvoltage clamp – Load current limitation – Self-limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Over-temperature shut-down with autorestart (thermal shut-down) A dedicated active low digital status pin is associated with every output channel in order to provide Enhanced diagnostic functions including fast detection of overload and short-circuit to ground, over-temperature indication, short-circuit to VCC diagnosis and ON & OFF state open-load detection. – Reverse battery protected (a) – Electrostatic discharge protection The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, over-temperature shut-off with autorestart and over-voltage active clamp. The diagnostic feedback of the whole device can be disabled by pulling the STAT_DIS pin up, thus allowing wired-ORing with other similar devices. a. See Application schematic.
