Power Features & Applications
- Integrates a low-quiescent-current synchronous buck driver with high-side and low-side OptiMOS 6 MOSFETs and an active Schottky-like diode structure.
- Reports on-chip MOSFET current with 3% accuracy and temperature telemetry for precise, temperature-compensated load monitoring.
- Supports Body-Braking mode via PWM tri-state signaling to quickly disable both MOSFETs and improve transient response.
- Provides automatic bootstrap capacitor replenishment to maintain gate-drive voltage and reliable startup.
- Delivers 70 A continuous output capability in a small 5 x 6 x 0.9 mm PQFN package for high-density VRMs.
- Features over-temperature protection and thermal shutdown with enhanced fault reporting for system safety.
