Preliminary Information
Dual Intelligent High-Current
Self-Protected Silicon High-Side
Switch (4.0 m
)
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 PQFN package with
exposed tabs.
