Freescale Semiconductor Document Number: MC33984 Rev. 16.0, 9/2014 Advance Information Dual Intelligent High-current Self-protected Silicon High-side 33984 Switch (4.0 mOhm The 33984 is a dual self-protected 4.0 mOhm silicon switch used to replace electromechanical relays, fuses, and discrete devices in power management HIGH-SIDE SWITCH 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 mm x 12 mm nonleaded BOTTOM VIEW PQFN package with exposed tabs.
