TPS259824LNRGER 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 input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |
| 2 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |
| 3 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |
| 4 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |
| 5 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |
| 6 | EN/UVLO | input | Active-high enable with an external resistor divider from IN to GND to set the UVLO threshold; it must not be left floating and its absolute maximum is 7 V. |
| 7 | ITIMER | output | A capacitor to GND sets the overcurrent blanking interval; leave it open for the fastest response, and shorting it to GND triggers a device fault. |
| 8 | ILIM | output | A resistor to GND sets the output current-limit and fast-trip thresholds; the recommended RILIM range is 82 Ω to 1650 Ω and the pin must not be left floating. |
| 9 | IMON | output | Analog load-current monitor output that sources current proportional to the load current (gain 246 µA/A typical); a resistor to GND converts it to a voltage. |
| 10 | RETRY_DLY | output | A capacitor to GND sets the delay before an automatic restart attempt after a fault; connecting this pin to GND selects latch-off with no auto-retry. |
| 11 | NRETRY | output | A capacitor to GND sets the number of automatic restart attempts after a fault; connecting this pin to GND selects infinite retries. |
| 12 | LDSTRT | input | Load-detect/handshake input where a capacitor to GND sets the time window in which the load must pull this pin low after PG asserts; connect to GND if unused and do not leave it floating. |
| 13 | PG | output | Active-high power-good open-drain output that requires an external pull-up, is asserted when the FET is fully enhanced and the output reaches its maximum voltage, and is held low when VIN is below VUVP. |
| 14 | GND | power_in | Ground connection to the system ground, used as the reference for all internal signals. |
| 15 | dVdt | output | A capacitor to GND sets the output turn-on slew rate; leave it open for the fastest slew rate during startup. |
| 16 | IN | power_in | Power input to the eFuse; the operating input range is 2.7 V to 24 V, with an absolute maximum of 30 V. |
| 17 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 18 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 19 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 20 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 21 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 22 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 23 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 24 | OUT | power_out | Power output to the load; the device can carry a continuous switch current of up to 15 A from IN to OUT. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
