Single Intelligent High-current
Self-protected Silicon High Side
Switch (2.0m
Ω)
The 33982B is a self-protected silicon 2.0m
Ω high side switch used
to replace electromechanical relays, fuses, and discrete devices in
power management applications. The 33982B 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 33982B is packaged in a power-enhanced 12 x 12 nonleaded
PQFN package with exposed tabs.
Features
• Single 2.0m
Ω max high side switch with parallel input or SPI
control
• 6.0V to 27V operating voltage with standby currents < 5.0
μA
• Output current monitoring with two SPI-selectable current ratios
• SPI control of over-current limit, over-current fault blanking time,
output-OFF open load detection, output ON/OFF control,
watchdog timeout, slew rates, and fault status reporting
• SPI status reporting of over-current, open and shorted loads,
over-temperature shutdown, under-voltage and over-voltage shutdown, fail-safe pin status, and program status
• Enhanced -16V reverse polarity VPWR protection
