Freescale Semiconductor
Advance Information
Document Number: MC33984
Rev. 9.0, 1/2007
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.
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.
