STMicroelectronics VN9D30Q100F 6-Channel Automotive High-Side Driver, based on VIPower technology, is optimized for driving resistive or inductive loads directly connected to ground. The device is protected against voltage transient on the VCC pin. Programming, control, and diagnostics are implemented via the SPI bus.
The VN9D30Q100F features digital current sense feedback for each channel, provided through an integrated 10-bit ADC with 0.1% of FSR. Dedicated trimming bits allow adjustment of the ADC reference current. The VN9D30Q100F is equipped with 6 outputs controllable via SPI or with the 2-OTP assignable direct inputs. The device detects open-load in OFF-state conditions. The VN9D, M0-9T technology devices feature digital current and chip temperature sensing for automotive applications powered by 12V battery tracks.
The VN9D30Q100F provides real-time diagnostics through the SPI bus. Output current limitation protects the device in an overload condition. The device can limit the dissipated power to a safe level up to thermal shutdown intervention. The thermal shutdown can be configured as latched off or programmable time-limited auto restart.
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.
The STMicroelectronics VN9D30Q100F 6-Channel High-Side Driver is available in a 6.0mm x 6.0mm QFN package. This device is AEC-Q100 qualified for use in automotive applications.
