VNQ7003SYTR

The VNQ7003SY 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 transient on VCCpin.An 8 bit short frame access to output control registers is provided allowing PWM control through SPI with high granularity.An analog current feedback for each channel is connected to the CURRENT-SENSE pin via a multiplexer. The device detects 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.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 this mode states of channel 0, 1, 2 or 3 are respectively controlled by four dedicated pins IN0, IN1, IN2 and IN3. Channel 0 and 1 can be programmed via SPI for load type (BULB/ LED mode).
