VN9D5D20FNTR

The VN9D5D20FN 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 transient on V_CC 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 with 0.1% of FSR. Dedicated trimming bits allow to adjust the ADC reference current. The device is equipped with four outputs controllable via SPI or with the 2-OTP assigned direct inputs. The device detects open-load in OFF-state conditions. Real-time diagnostic is available through the SPI bus (open-load, output short to V_CC, 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. The device enters a limp-home mode in case of loss of digital supply (V_DD), 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.
