TPS259823LNRGET 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, one of multiple power input pins including thermal pad for heat dissipation and current distribution. |
| 2 | IN | power_in | Power supply input, one of multiple power input pins including thermal pad for heat dissipation and current distribution. |
| 3 | IN | power_in | Power supply input, one of multiple power input pins including thermal pad for heat dissipation and current distribution. |
| 4 | GND | power_in | Ground connection to system ground reference plane. |
| 5 | GND | power_in | Ground connection to system ground reference plane. |
| 6 | EN/UVLO | input | High-level active enable pin with external resistor divider from IN to GND for setting under-voltage lockout threshold; must not be left floating, recommended voltage 6V maximum. |
| 7 | ITIMER | output | Analog output pin with external capacitor to GND setting overcurrent blanking interval; allows temporary overcurrent up to 2.1× ILIM before circuit protection activates. |
| 8 | ILIM | output | Analog output pin with external resistor to GND (82Ω to 1650Ω) setting output current limit threshold from 2A to 15A and fast trip threshold at 2.1× ILIM; must not be left floating. |
| 9 | IMON | output | Analog load current monitor output with gain of 246 µA/A; provides current proportional to output load current, convertible to voltage by external resistor to GND. |
| 10 | RETRY_DLY | output | Analog output pin with external capacitor to GND setting time delay from fault shutdown to automatic restart attempt; connect to GND for latching mode without auto-retry. |
| 11 | NRETRY | output | Analog output pin with external capacitor to GND setting number of automatic restart attempts after fault; connect to GND for infinite retry operation. |
| 12 | LDSTRT | input | Load detection/handshake signal input with external capacitor to GND setting time window for external circuit to pull this pin low after PG assertion; must not be left floating. |
| 13 | PG | output | High-level active power good open-drain digital output asserted when FET is fully on and output voltage reaches maximum; requires external pull-up resistor, remains low when VIN < VUVP. |
| 14 | GND | power_in | Ground connection to system ground reference plane. |
| 15 | dVdt | output | Analog output pin with external capacitor to GND for setting output voltage slew rate during startup to manage inrush current; leave floating for maximum slew rate. |
| 16 | IN | power_in | Power supply input, one of multiple power input pins including thermal pad for heat dissipation and current distribution. |
| 17 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 18 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 19 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 20 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 21 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 22 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 23 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 24 | OUT | power_out | Power supply output from integrated electronic fuse, one of multiple output pins rated for 15A maximum continuous current. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
