Overview
The VN9D5D20FNTR is a 4-channel high-side driver developed by STMicroelectronics using their VIPower technology. This device is designed to drive resistive or inductive loads directly connected to the ground, making it suitable for various automotive applications. It features a 24-bit SPI interface for programming, control, and diagnostics. The device is protected against voltage transients on the VCC pin and includes advanced diagnostic capabilities through the SPI bus, such as open-load detection, output short to VCC, overtemperature, communication errors, and power limitation or latch-off conditions.
The VN9D5D20FNTR also includes an integrated 10-bit ADC for digital current sense feedback with 0.1% of Full Scale Range (FSR) accuracy. It supports multiple operating modes, including reset, fail-safe, normal, standby, and sleep modes, ensuring robust fail-safe functionality. The device is AEC-Q100 qualified and compliant with European directive 2002/95/EC, making it a reliable choice for automotive systems.
