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.
