Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Supply input accepting 2.7V to 24V (absolute maximum 30V) with integrated thermal pad for device power distribution and heat dissipation. |+| 2 | IN | power_in | Supply input accepting 2.7V to 24V (absolute maximum 30V) with integrated thermal pad for device power distribution and heat dissipation. |+| 3 | IN | power_in | Supply input accepting 2.7V to 24V (absolute maximum 30V) with integrated thermal pad for device power distribution and heat dissipation. |+| 4 | GND | power_in | Ground reference connection for the device. |+| 5 | GND | power_in | Ground reference connection for the device. |+| 6 | EN/UVLO | input | Enable/UVLO analog input rated 6V maximum with adjustable UVLO threshold (1.2V typical rising, 1.1V typical falling) via external resistor divider to GND; do not leave floating. |+| 7 | ITIMER | output | Overcurrent blanking timer output with internal voltage limiting; external capacitor to GND sets blanking interval; leave open for minimum delay response. |+| 8 | ILIM | output | Current limit threshold output requiring external resistor (82Ω to 1650Ω) to GND to set 2A to 15A current limit and fast-trip threshold; do not leave floating. |+| 9 | IMON | output | Current monitor analog output providing 246 µA/A transimpedance for load current measurement; connect resistor to GND to convert to voltage signal. |+| 10 | RETRY_DLY | output | Automatic retry delay timing output with internal voltage limiting and 2.05 µA bias current; external capacitor to GND sets retry delay interval; connect to GND for latch-off. |+| 11 | NRETRY | output | Automatic retry count output with internal voltage limiting and 2.05 µA bias current; external capacitor to GND sets number of retry attempts after fault shutdown. |+| 12 | LDSTRT | input | Load detect/handshake input with VLDSTRT threshold of 1.21V typical; capacitor to GND sets handshake window after PG assertion to prevent false latch-off; do not leave floating. |+| 13 | PG | output | Power good open-drain output with typical 4.2 mΩ on-resistance when asserted; indicates FET fully enhanced and output at maximum voltage; remains low when VIN < VUVP. |+| 14 | GND | power_in | Ground reference connection for the device. |+| 15 | dVdt | output | Output slew rate control with capacitor voltage rating (VIN + 4V) and 4.6 µA charging current; external capacitor to GND slows rise time; leave floating for fastest slew rate. |+| 16 | IN | power_in | Supply input accepting 2.7V to 24V (absolute maximum 30V) with integrated thermal pad for device power distribution and heat dissipation. |+| 17 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 18 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 19 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 20 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 21 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 22 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 23 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 24 | OUT | power_out | Output connection rated up to (VIN + 0.3V) providing regulated power with typical on-resistance of 2.7 mΩ and maximum sustained current of 15A. |+| 25 | EP | passive | Exposed pad (from the footprint;
