NCV7750
NCV7750
Quad Low-Side Relay Driver
The NCV7750 is an automotive four channel lowside driver
providing drive capability up to 600 mA per channel. Output control is
via a SPI port and offers convenient reporting of faults for open load
(or short to ground), overload, and overtemperature conditions.
Additionally, parallel control of the outputs is addressable (in pairs)
via the INx pins.
A dedicated limphome mode pin (LHI) enables OUT1OUT4.
Each output driver is protected for overload current and includes an
output clamp for inductive loads.
The NCV7750 is available in a SSOP24 fused lead package.
