STMicroelectronics VN9D30Q100F High-Side Driver
Features a 24-bit SPI interface for the automotive sector
The VN9D30Q100F by STMicroelectronics is a 6-channel high-side driver intended for driving resistive or inductive loads directly connected to ground.
Made using STMicroelectronics’ VIPower technology, the device features a digital current sense feedback for each channel, which is provided through an integrated 10-bit ADC with 0.1% of FSR. Dedicated trimming bits allow for ADC reference current adjustment.
With protection against voltage transient on VCC pin, the VN9D30Q100F is equipped with 6 outputs controllable via SPI or with the 2-OTP assignable direct inputs, while also detecting open-load in OFF-state conditions.
Real time diagnostic is available through the SPI bus (open-load, output short to VCC, overtemperature, communication error, power limitation or latch off).
Output current limitation protects the device in an over load condition. The device can limit the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown can be configured as latched off or programmable time limited auto restart.
Limp home mode
The device enters a limp home mode in case of loss of digital supply (VDD), reset of digital memory or watchdog monitoring time-out event. In limp home mode, each output is set according to the programmed register: to be always OFF, or according to the 2x direct inputs pins.
