Technical Data
Single High Side Switch
(4.0 mOhm), PWM clock up to
60 kHz
The 33981 is a high frequency, self-protected 4.0 m ? R DS(ON) high
side switch used to replace electromechanical relays, fuses, and
discrete devices in power management applications.
The 33981 can be controlled by pulse-width modulation (PWM) with
a frequency up to 60 kHz. It is designed for harsh environments, and it
includes self-recovery features. The 33981 is suitable for loads with high
inrush current, as well as motors and all types of resistive and inductive
loads.
The 33981 is packaged in a 12 x 12 mm non-leaded power-enhanced
PQFN package with exposed tabs.
Features
? Single 4.0 m ? R DS(ON) maximum high side switch
? PWM capability up to 60 kHz with duty cycle from 5% to 100%
? Very low standby current
? Slew-rate control with external capacitor
? Over-current and over-temperature protection, under-voltage
shutdown, and fault reporting
