This document introduces the features and characteristics of the VNQ5E050K-E product, including general features, diagnostic functions, protection functions and application scenarios
The VNQ5E050K-E is a quad channel high-side driver manufactured by STMicroelectronics using proprietary ViPower™ MO-5 technology. It is housed in a tiny PowerSSO-24 package and is designed to drive automotive grounded loads while delivering protection, diagnostics, and an easy 3 V and 5 V CMOS compatible interface with microcontrollers.
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 to provide enhanced diagnostic functions including fast detection of overload and short-circuit to ground, over temperature indication, and open-load detection.
