Power Features & Applications
- Integrates a synchronous buck gate driver, active diode, and high-side and low-side MOSFETs into a single compact module to minimize parasitic inductance.
- Reports accurate on-chip temperature with an 8 mV/degC gain for real-time thermal monitoring across multiple power stages.
- Provides MOSFET current reporting via a 5 uA/A signal with +/-5% accuracy, removing the need for lossy DCR or sense-resistor sensing.
- Delivers 20 A continuous output current with 36 A over-current protection for robust fault handling.
- Offers auto-sleep and deep-sleep modes that significantly lower quiescent current under light-load conditions.
- Includes high-side MOSFET short-circuit detection and a fault flag for enhanced system-level protection.
