Overview
The VNQ7003SYTR is a quad-channel high-side driver developed by STMicroelectronics using their VIPower technology. This device is designed to drive resistive or inductive loads directly connected to ground. It features an 8-bit short frame access to output control registers, allowing for PWM control through an SPI interface with high granularity. The device includes advanced diagnostic capabilities, including real-time diagnostics via the SPI bus for conditions such as open-load, output short to VCC, overtemperature, communication errors, power limitation, or latch-off. It also includes output current limitation and thermal shutdown protection, which can be configured for latched off or programmable time-limited auto-restart.
