The STMicroelectronics VN9E30F is a device made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads directly connected to ground. The device is protected against voltage transient on the VCC pin (see ISO7637 transient compatibility table). Programming, control and diagnostics are implemented via the SPI bus. A digital current sense feedback for each channel is provided through an integrated 10-bit ADC with 0.1% of FSR. Dedicated trimming bits allow to adjust the ADC reference current. The device detects open-load in OFF-state conditions. Real time diagnostics is available through the SPI bus (open-load, output short to VCC, over temperature, communication error, power limitation or latch off). Output current limitation protects the device in an overload condition.
