Preliminary Information
Single Intelligent High-Current
Self-Protected Silicon High-Side
Switch (2.0 mΩ)
The 33982 is a self-protected silicon 2.0 mΩ high-side switch used to
replace electromechanical relays, fuses, and discrete devices in power
management applications. The 33982 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 the output. SPI programmable
fault trip thresholds allow the device to be adjusted for optimal performance in
the application.
The 33982 is packaged in a power-enhanced 12 x 12 PQFN package with
exposed tabs.
