NCV7510 Datasheet, PDF (1/22 Pages) ON Semiconductor – FlexMOS Programmable Peak and Hold PWM MOSFET Predriver

NCV7510
FlexMOSt Programmable
Peak and Hold PWM
MOSFET Predriver
The NCV7510 high side MOSFET predriver is a fully
programmable automotive grade product for driving solenoids or
other unipolar actuators. The product is optimized for common−rail
diesel fuel injection applications and includes an additional
synchronous clamp MOSFET predriver. Peak and hold currents, peak
dwell time and other features are programmable via the device’s SPI
port. Load current is continuously sampled and compared to the
programmable 7−bit peak/hold DAC values while the load
self−modulates to maintain the desired currents at each of the peak and
hold points. Passive fault diagnostics monitor and protect the
MOSFETs when a fault is detected. Fault data is available via SPI and
an open−drain FAULT output provides immediate fault notification to
a host controller.
The FlexMOS family of products offers application scalability
through choice of external MOSFETs.
