Description
The VNQ5E160K-E is a quad channel high-side driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny PowerSSO-24 package. The VNQ5E160K-E is designed to drive automotive grounded loads delivering protection, diagnostics and easy 3V and 5V 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, over temperature shut-off with auto restart and over-voltage active clamp. 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. 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.

This solution can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1. 2. RGND ≤ 600mV / (IS(on)max). RGND ≥ (−VCC) / (-IGND)
where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. Power dissipation in RGND (when VCC
