MC3399 Datasheet Automotive Half-amp High-side Switch

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Order this document by MC3399/D MC3399 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 patible 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.

Key Features

  • of Bipolar and MOS technologies. The mixed technology provides higher gain PNP output devices and results in Power Integrated Circuits having substantially reduced quiescent currents. The device operates over a wide power supply voltage range and can withstand voltage transients (positive or negative) of ±100 V. A rugged PNP output stage along with active clamp circuitry, output current limit and thermal shutdown permit the driving of all types of loads, including inductive. The MC3399 is offere.
