TPS259827ONRGET from Texas Instruments, in a VQFN-24(4x4). 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; do not leave floating. |
| 9 | IMON | output | Analog load current monitor providing output current proportional to load current with gain 246 µA/A typical at ±1.5% accuracy; resistor to GND converts to voltage signal for ADC. |
| 10 | RETRY_DLY | output | Capacitor to GND sets delay time from fault shutdown to automatic restart per tRETRY_DLY = 128 × CRETRY_DLY / IRETRY_DLY; connect to GND for latch mode without auto-retry. |
| 11 | NRETRY | output | Capacitor to GND sets number of automatic restart attempts after fault with discrete levels at 4, 16, 64, 256, 1024 retries; 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; leave floating for fastest slew rate and minimum startup time. |
| 16 | IN | power_in | Power supply input voltage range 2.7V to 24V; part of multi-pin input connection. |
| 17 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 18 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 19 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 20 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 21 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 22 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 23 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 24 | OUT | power_out | Power supply output, maximum continuous current 15A; integrated MOSFET switch with 2.7mΩ typical on-resistance at 25°C. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
