Dual intelligent high-current

self-protected silicon high-side

switch (4.0 mOhm

33984

The 33984 is a dual self-protected 4.0 mOhm silicon switch used to replace

electromechanical relays, fuses, and discrete devices in power management

applications. The 33984 is designed for harsh environments, and it includes

self-recovery features. The device is suitable for loads with high inrush current,

as well as motors and all types of resistive and inductive loads.

HIGH-SIDE SWITCH

Programming, control, and diagnostics are implemented via the serial

peripheral interface (SPI). A dedicated parallel input is available for alternate

and pulse-width modulation (PWM) control of each output. SPI-programmable

fault trip thresholds allow the device to be adjusted for optimal performance in

the application.

The 33984 is packaged in a power-enhanced 12 mm x 12 mm nonleaded

PQFN package with exposed tabs.
