SEMICONDUCTOR TECHNICAL DATA

Preliminary Information

33987

Quad Intelligent High-Side Switch

(Quad 70 mΩ)

The 33987 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 70 mΩ) can control the high sides of four separate resistive or

inductive loads.

QUAD INTELLIGENT

HIGH-SIDE SWITCH

Programming, control, and diagnostics are accomplished using a 16-bit SPI

interface. Additionally, each output has its own parallel input for PWM control

if desired. The 33987 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 33987 is packaged in a power-enhanced 10x10 nonleaded Power

QFN package with exposed tabs.
