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 within recommended range 2.7V to 24V (absolute maximum 30V); exposed pad must be soldered evenly to input power plane to provide proper thermal dissipation and maintain ideal current distribution. |+| 2 | IN | power_in | Power supply input within recommended range 2.7V to 24V; exposed pad must be soldered evenly to input power plane for proper thermal dissipation and current distribution. |+| 3 | IN | power_in | Power supply input within recommended range 2.7V to 24V; exposed pad must be soldered to input power plane for current distribution and thermal management. |+| 4 | GND | power_in | Ground connection to system ground plane; provides DC return path and signal reference for all internal circuits. |+| 5 | GND | power_in | Ground connection to system ground plane; provides return path for internal circuits and external connections. |+| 6 | EN/UVLO | input | Device enable pin (high-level active) with maximum input voltage of 7V; external resistive voltage divider from IN to GND can set under-voltage lockout threshold above factory default VUVLO(R) of 1.2V; do not leave floating. |+| 7 | ITIMER | output | Overcurrent blanking timer output; capacitor connected to GND sets blanking interval during which output current can temporarily exceed programmed current limit up to 2.1×ILIM before circuit breaker responds; leave open for fastest response. |+| 8 | ILIM | output | Current limit and fast-trip threshold setting; external resistor to GND in range 82Ω to 1650Ω sets output current limit threshold from 2A to 15A with ±8% typical accuracy; fast-trip threshold set at 2.1×ILIM; do not leave floating. |+| 9 | IMON | output | Analog load current monitor output providing current proportional to output current flowing through FET with gain of 246µA/A and ±1.5% typical accuracy for IOUT > 3A; connect series resistor to GND to convert current signal to voltage. |+| 10 | RETRY_DLY | output | Automatic retry delay timer output; capacitor to GND sets time interval from fault shutdown until device attempts automatic restart; connect to GND for latch-off operation (no automatic retry). |+| 11 | NRETRY | output | Automatic retry counter output; capacitor to GND sets number of automatic restart attempts after fault (quantized to discrete values: 4, 16, 64, 256, or 1024 attempts); connect to GND for unlimited automatic retries. |+| 12 | LDSTRT | input | Load detect handshake signal input with voltage threshold at 1.1V to 1.3V; capacitor to GND sets time window following PG assertion during which load circuit must pull this pin low to maintain device conduction; connect to GND if load detection not used; do not leave floating. |+| 13 | PG | output | Power-good indicator output (active high open-drain with 4.2mΩ typical ON-resistance); asserted when FET is fully enhanced with gate drive at VIN + 3.6V and output reaches maximum voltage; remains at logic low when VIN < VUVP. |+| 14 | GND | power_in | Ground connection to system ground plane; ensures low-impedance return path for all internal and external circuits. |+| 15 | dVdt | output | Output voltage slew rate control output; capacitor to GND sets output voltage rise time during turn-on to limit inrush current (calculate capacitor as 4600pF ÷ SR in V/ms); leave floating for fastest slew rate (7.4V/ms typical at 24V VIN). |+| 16 | IN | power_in | Power supply input connection (2.7V to 24V) providing secondary input current path; exposed pad must be soldered to input power plane to distribute current and dissipate heat. |+| 17 | OUT | power_out | Power supply output providing switched power to load with maximum output voltage of VIN + 0.3V; supports continuous current up to 15A with integrated over-current and short-circuit protection. |+| 18 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A with integrated protection. |+| 19 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 20 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 21 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 22 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 23 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 24 | OUT | power_out | Power supply output providing switched power to load; supports continuous output current up to 15A. |+| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | QFN-24(4x4) |+| Category | Circuit Protection |+| Pins | 25 |++## CAD (KiCad official)++- Symbol: `TPS259824ONRGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.6x2.6mm`+- 3D model: QFN-24(4x4) (KiCad packages3D, STEP)+- 3D model files: `tps259824onrger-etched.step` / `tps259824onrger-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
