NCV7754中文资料Octal Low-side Relay Driver, Eight Channel数据手册ONSEMI规格书

描述 Description

The NCV7754 is an automotive eight channel low−side driver
providing drive capability up to 500 mA per channel. Output control is
via a SPI port and offers convenient reporting of faults for open load
(or short to ground), over load, and over temperature conditions.
Additionally, parallel control of the outputs is addressable (in pairs)
via the INx pins.
A dedicated limp−home mode pin (LHI) enables OUT1−OUT4
while disabling OUT5−OUT8.
Each output driver is protected for over load current and includes an
output clamp for inductive loads.
The NCV7754 is available in a SSOP−24 fused lead package.
