Technical Data
Dual Intelligent High-current
Self-protected Silicon High Side
Switch (4.0 mOhm ?
The 33984 is a dual self-protected 4.0 m ? 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 mm
nonleaded PQFN package with exposed tabs.
