STMicroelectronics EV-VN9D30Q100F Evaluation Board
STMicroelectronics EV-VN9D30Q100F Evaluation Board provides an easy way to connect ST VIPower M0-9SPI technology to existing systems. The EV-VN9D30Q100F comes pre-assembled with VN9D30Q100F high-side driver. An onboard minimum set of electrical components (per the device datasheet recommendation) enables the user to directly connect the load, power supply, and microcontroller without additional effort in external component design and connection.
The VN9D30Q100F 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 transients on the VCC pin. Programming, control, and diagnostics are implemented via the SPI bus.
Digital current sense feedback for each channel is provided through an integrated 10-bit ADC with 0.1% FSR. Dedicated trimming bits allow adjustment of the ADC reference current. The device has six outputs controllable via SPI or with the 2-OTP assignable direct inputs.
The device detects open-load in OFF-state conditions. Real-time diagnostics are available through the SPI bus (open-load, output short to VCC, overtemperature, communication error, power limitation, or latch-off). The 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. 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 always be OFF or according to the 2x direct input pins.
