Quad High-Side Switch
(Quad 15 m)
33580
The 33580 is one in a family of devices designed for low-voltage
automotive and industrial lighting and motor control applications. Its
four low RDS(ON) MOSFETs (four 15 m) can control the high sides of
four separate resistive or inductive loads.
Programming, control, and diagnostics are accomplished using a
16-bit SPI interface. Additionally, each output has its own parallel input
for pulse-width modulation (PWM) control if desired. The 33580 allows
the user to program via the SPI the fault current trip levels and duration
of acceptable lamp inrush or motor stall intervals. Such
programmability allows tight control of fault currents and can protect
wiring harnesses and circuit boards as well as loads.
The 33580 is packaged in a power-enhanced 12x 12 nonleaded
Power QFN package with exposed tabs.
