1 Features

• Wide operating input voltage range: 3.5V to 23V

– 28V absolute maximum

– Can be powered from either IN or OUT

• Integrated back-to-back FETs with low ONresistance: RON = 12.2mΩ (typical)

• Ideal diode operation with true reverse current blocking (RCB)

– External pin control (RCBCTRL) to disable RCB and allow bi-directional power delivery in steady-state to support USB OTG or DRP operation

• Fast overvoltage protection

– Adjustable overvoltage lockout (OVLO) with 1μs (typical) response time

• Overcurrent protection with load current monitor output (ILM)

– Active current limit response

– Adjustable threshold (ILIM) 1A–9A

• ±10% accuracy (maximum) for ILIM > 3A

– Adjustable transient blanking timer (ITIMER) to allow peak currents > ILIM

– Output load current monitor accuracy: ±6% (typical) (IOUT ≥ 3A)

• Fast-trip response for short-circuit protection

– < 1μs (typical) response time

– Adjustable and fixed thresholds

• Active high enable input with adjustable undervoltage lockout threshold (UVLO)

• Adjustable output slew rate control (dVdt)

• Overtemperature protection

• Digital outputs: Supply Good (SPLYGD/SPLYGD) and Fault Indication (FLT)

• UL 2367 recognition (planned)

• IEC 62368-1 CB certification (planned)

• IEC 61000-4-5: 28V on IN

• Small footprint: PowerWCSP 2.4mm × 1.7mm, 0.5mm pitch
