Dual Intelligent High-current

Self-protected Silicon High Side

Switch (8.0m

Ω)

The 33988 is a dual self-protected 8.0m

Ω silicon switch used to

replace electromechanical relays, fuses, and discrete devices in

power management applications. The 33988 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 33988 is packaged in a power-enhanced 12 x 12 nonleaded

PQFN package with exposed tabs.

Features

• Dual 8.0m

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 overcurrent, open and shorted loads, over-

temperature, under-voltage and over-voltage shutdown, fail-safe

pin status, and program status

• Enhanced -16V reverse polarity VPWR protection
