WAKE
The MC33982 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 MC33982 is designed
for harsh environments and includes selfrecovery 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 MC33982 is packaged in a powerenhanced 12 x 12 mm non-leaded PQFN
package with exposed tabs.
