The TDA21520 OptiMOS™ power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with high-side and low-side MOSFETs and an active diode structure that achieves low Vsd similar to a Schottky with very little reverse recovery charge. The TDA21520 internal MOSFET current sense algorithm with temperature compensation achieves superior current sense accuracy versus inductor DCR sense methods.

Features

  • Integrated driver, diode & 2 MOSFETs
  • Input voltage range of 4.25 V to 16 V
  • Vcc & Vdrv supply of 4.25 V to 5.5 V
  • Output voltage range from 0.25-5.5 V
  • On-chip MOSFET current reporting 5 µA/A
  • 20A operating current with 36A OCP
  • Operation up to 1.5 MHz
  • High-side MOSFET short detection & flag
  • Thermal shutdown
  • Cycle-by-cycle OCP & fault flag
  • Auto-sleep & Deep-sleep modes
  • Compatible with 3.3V tri-state PWM input

Benefits

  • High efficiency at low o/p voltage
  • Accurate current reporting
  • fault monitoring for robustness
  • Bootstrap cap auto-replenishment
  • Optimized PCB heat transfer
