Dual Intelligent High-Current

Self-Protected Silicon

High-Side Switch (4.0 mΩ)

33984B

The 33984 is a dual self-protected 4.0 mΩ 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.

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 x 12 nonleaded

PQFN package with exposed tabs.
