ST VNQ6004SA-E

通用425A，55A

Overview

The VNQ6004SA-E is a device made using STMicroelectronicsVIPowertechnology. It is intended for driving resistive or inductive loads directly connected to ground. The device is protected against voltage transient on VCCpin.

Programming, control and diagnostics are implemented via the SPI bus. An analog current feedback for each channel is connected to the CURRENT-SENSE pin via a multiplexer. A CS_SYNC pin delivers a synchronous signal for sampling the current sense while the corresponding output is on. The device detects open-load for both on and OFF-state conditions. Real time diagnostic is available through the SPI bus (open-load, output short to VCC, over temperature, communication error, power limitation). 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 with automatic restart. The device enters a limp home mode in case of loss of digital supply (VDD), reset of digital memory or CSN 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 0,1 can be programmed in BULB/LED mode.
