Advance Information
Document Number:
MC33874
Rev. 8.0, 4/2007
Quad High-Side Switch
(Quad 35 m鈩?
The 33874 is one in a family of devices designed for low-voltage
automotive and industrial lighting and motor control applications. Its
four low R
DS(ON)
MOSFETs (four 35 m鈩? 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 33874
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 33874 is packaged in a power-enhanced 12 x 12 nonleaded
Power QFN package with exposed tabs.
