Description

The VNQ6040S-E 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 VCC pin.

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-state

and off-state conditions.

Real time diagnostic is available through the SPI

bus (open-load, output short to VCC,

overtemperature, communication error).

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 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. Each channel can be

programmed in BULB/LED mode.
