TPS259804ONRGER from Texas Instruments, in a VQFN-24-EP(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 | Input power supply connection for 2.7V to 24V operation. |
| 2 | IN | power_in | Input power supply connection for 2.7V to 24V operation. |
| 3 | IN | power_in | Input power supply connection for 2.7V to 24V operation. |
| 4 | GND | power_in | Ground return connection to system ground. |
| 5 | GND | power_in | Ground return connection to system ground. |
| 6 | EN/UVLO | input | High-level active enable pin with external voltage divider to IN and GND for adjustable UVLO threshold; do not leave floating. |
| 7 | ITIMER | output | Analog output for overcurrent blanking; external capacitor to GND sets interval duration before circuit breaker operation. |
| 8 | ILIM | output | Analog output for current limit setting; external resistor to GND (182Ω to 1650Ω range) sets output current limit threshold. |
| 9 | IMON | output | Analog load current monitor output providing 246µA/A current gain; external resistor to GND converts to voltage signal. |
| 10 | RETRY_DLY | output | Analog output for automatic retry delay; external capacitor to GND sets time interval between fault shutdown and restart attempts. |
| 11 | NRETRY | output | Analog output for retry count; external capacitor to GND sets maximum number of automatic restart attempts after fault. |
| 12 | LDSTRT | input | Analog input for load detection and handshake signal; external capacitor to GND sets startup verification window duration. |
| 13 | PG | tri_state | Digital open-drain power good output indicating FET fully enhanced and output at maximum voltage; requires external pull-up resistor. |
| 14 | GND | power_in | Ground return connection to system ground. |
| 15 | dVdt | output | Analog output for output voltage slew rate control; external capacitor to GND sets rise time during turn-on to manage inrush current. |
| 16 | IN | power_in | Input power supply connection for 2.7V to 24V operation; includes exposed thermal die pad connection. |
| 17 | OUT | power_out | Output power connection for load supply. |
| 18 | OUT | power_out | Output power connection for load supply. |
| 19 | OUT | power_out | Output power connection for load supply. |
| 20 | OUT | power_out | Output power connection for load supply. |
| 21 | OUT | power_out | Output power connection for load supply. |
| 22 | OUT | power_out | Output power connection for load supply. |
| 23 | OUT | power_out | Output power connection for load supply. |
| 24 | OUT | power_out | Output power connection for load supply. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
