33984

Dual Intelligent High-Current

Self-Protected Silicon High-Side

Switch (4.0 mΩ)

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.

DUAL HIGH-SIDE SWITCH

4.0 mΩ

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.

Bottom View

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

package with exposed tabs.
