TDA21570, 70 A integrated power stage, contains a low quiescent current synchronous buck gate-driver IC. In addition, the TDA21570 combines control & synchronous MOSFETs along with an active diode structure for low Vsd similar to a Schottky Diode with very little reverse recovery charge. The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing when layout guidelines are followed.

Features

  • Integrated driver, diode & 2 MOSFETs
  • On-chip MOSFET current reporting 5 µA/A
  • Input voltage range of 4.25 V to 16 V
  • Output current capability of 70 A
  • Enhanced Fault report & identification
  • OTP and thermal shutdown
  • Bootstrap capacitor Auto-replenishment
  • Compatible with 3.3V tri-state PWM Input
  • DEEP SLEEP power saving (32 µA typ)
  • Small 5 mm x 6 mm x 0.9 mm PQFN package

Benefits

  • High efficiency
  • Industry best current accuracy
  • Enhanced fault identification
  • Advanced protection features
  • Low Iq for power saving via EN=low
