Rev. 8.0, 4/2007
Quad High-Side Switch (Quad 35 mΩ)
The 33874 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 35 mΩ) 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.
