Technical Data

Dual Intelligent High-current

Self-protected Silicon High Side

Switch (4.0 mOhm

)

The 33984 is a dual self-protected 4.0 m

Ω 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 mm

nonleaded PQFN package with exposed tabs.

Features

• Dual 4.0 m

Ω max 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 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, under-voltage and over-voltage shutdown, fail-safe

pin status, and program status

• Enhanced -16 V reverse polarity VPWR protection
