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
