Features and benefits

  • Low collector-emitter saturation voltage VCEsat
  • High collector current capability IC and ICM
  • High collector current gain (hFE ) at high IC
  • High efficiency leading to reduced heat generation
  • Reduced printed-circuit board area requirements.


  • Power management:
    • DC-DC converter
    • Supply line switching
    • Battery charger
    • LCD back lighting.
  • Peripheral driver:
    • Driver in low supply voltage applications (e.g. lamps and LEDs)
    • Inductive load drivers (e.g. relay, buzzers and motors).
