EV-VNF9Q20F

EV-VNF9Q20F is a VNF9Q20F evaluation board. It comes preassembled with EV-VNF9Q20F high-side driver. On board a minimum set of electrical components is enabling the user to directly connect the load, the power supply and the microcontroller without any additional effort in external component design and connection. The VNF9Q20F is a device made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads directly connected to the ground. The device is protected against voltage transients on the VCC pin. 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. Dedicated trimming bits allow adjusting the ADC reference current. The device is equipped with 4 outputs controllable via SPI or 2-OTP assignable direct inputs. Suitable 4-channel high-side driver with STi²Fuse protection for automotive power distribution applications.
