Automotive Half-Amp High-Side Switch

The MC3399 is a High–Side Switch designed to drive loads from the positive side of the power supply. The output is controlled by a TTL compatible input Enable pin. In the “on” state, the device exhibits very low saturation voltages for load currents in excess of 750 mA. The device isolates the load from positive or negative going high voltage transients by abruptly “opening” thus protecting the load from the transient voltage for the duration of the transient. The device automatically re–establishes its original operating state following the transient condition.
