Document order number: MC33982/D
Rev 7.0, 03/2004
Preliminary Information
Single Intelligent High-Current
Self-Protected Silicon High-Side
Switch (2.0 mΩ)
The 33982 is a self-protected silicon 2.0 mhigh-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.
Features
• Single 2.0 mMax High-Side Switch with Parallel Input or SPI Control
• 6.0 V to 27 V Operating Voltage with Standby Currents < 5.0 µA
• Output Current Monitoring Output with Two SPI-Selectable Current
Ratios
• SPI Control of Overcurrent Limit, Overcurrent Fault Blanking Time,
Output-OFF Open Load Detection, Output ON/OFF Control, Watchdog
Timeout, Slew Rates, and Fault Status Reporting
• SPI Status Reporting of Overcurrent, Open and Shorted Loads,
Overtemperature Shutdown, Undervoltage and Overvoltage Shutdown,
Fail-Safe Terminal Status, and Program Status
• Enhanced 16 V Reverse Polarity VPWR Protection
