Single High Side Switch
(4.0 mOhm), PWM clock up to
60 kHz
side switch used to replace electromechanical relays, fuses, and
discrete devices in power management applications.
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.
PQFN package with exposed tabs.
