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 | Power supply input voltage range 2.7V to 24V; exposed thermal pad must be evenly soldered to input power plane for proper heat dissipation and optimal current distribution. |+| 2 | IN | power_in | Power supply input voltage range 2.7V to 24V; exposed thermal pad must be evenly soldered to input power plane for proper heat dissipation and optimal current distribution. |+| 3 | IN | power_in | Power supply input voltage range 2.7V to 24V; exposed thermal pad must be evenly soldered to input power plane for proper heat dissipation and optimal current distribution. |+| 4 | GND | power_in | Ground connection to system ground plane. |+| 5 | GND | power_in | Ground connection to system ground plane. |+| 6 | EN/UVLO | input | High-level active enable pin; resistor voltage divider from input power to GND adjusts UVLO threshold per VINUVLO = VUVLO(R) × (RVL1 + RVL2) / RVL2, do not leave floating. |+| 7 | ITIMER | output | Capacitor to GND sets overcurrent blanking interval during which output current may temporarily exceed ILIM but remain below 2.1×ILIM threshold before circuit breaker activation; leave open for fastest response. |+| 8 | ILIM | output | External resistor to GND sets output current limit threshold ILIM and fast-trip threshold per RILIM = 1460/(ILIM - 0.11) with range 82Ω to 1650Ω;

connect to GND for infinite retry attempts. |+| 12 | LDSTRT | input | Load detection/handshake signal; capacitor to GND sets time window requiring load to pull pin low after PG valid per tLDSTRT = CLDSTRT × VLDSTRT / ILDSTRT; connect to GND if feature not used, do not leave floating. |+| 13 | PG | tri_state | High-level active power good indicator, open-drain output requiring external pull-up resistor to external power; valid when FET fully enhanced and output reaches full voltage, stays low when VIN < VUVP. |+| 14 | GND | power_in | Ground connection to system ground plane. |+| 15 | dVdt | output | Capacitor to GND sets output turn-on slew rate limiting inrush current per CdVdt = 4600/SR with bias voltage internal;
