Advance Information
Dual Intelligent High-Current
Self-Protected Silicon High-Side
Switch (4.0 m鈩?
The 33984 is a dual self-protected 4.0 m鈩?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.

Freescale Semiconductor, Inc...
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.
