BTS7008-2EPA

BTS7008-2EPA
PROFET™+2 High-side switch for energy efficiency and miniaturization
BTS7008-2EPA is the lead product of the new PROFET™+2 family of single-, dual-and quad-channel protected high-side power switches (8 mΩ to 200 mΩ). The family offers benchmark form factor, the lowest RDS(on) (2 x 8 mΩ) and smallest package (TSDSO-14) pin pitch of 0.65 mm.
Key Features Key Applications
  • ReverSave™ for low power dissipation in reverse polarity
  • New intelligent restart control for:
    • Absolute and dynamic temperature limitation
    • Over current protection (tripping)
  • Cranking capability down to 3.1 V
  • Open Load in ON and OFF state
  • AECQ100
  • Automotive 12 V lighting load applications capacitive loads e.g. halogen bulbs and LED modules
  • Resistive loads e.g. small seat heating applications requiring below 8 A nominal current
