TPS2140IPWPR
Texas Instruments · Power Distribution Switches · HTSSOP-14-EP
TPS2140IPWPR from Texas Instruments, in a HTSSOP-14-EP. 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 | SW_PG | output | Switch power-good output, active-high CMOS logic level that goes low when SW_OUT is undervoltage (below 88% of 3.3 V for TPS2140), and needs no external pullup. |
| 2 | SW_IN | input | Input of the integrated N-channel power switch (65 mΩ maximum on-state resistance, 500 mA continuous); pins 2 and 3 are both SW_IN. |
| 3 | SW_IN | input | Second input pin of the power switch, connected in parallel with pin 2 for SW_IN. |
| 4 | LDO_IN | input | Input of the internal LDO, which has a 0.5 V maximum dropout and is rated for 250 mA continuous current; also one of the two inputs for internal VCC selection. |
| 5 | SW_EN | input | Switch enable input that is active low for TPS2140 (internal pullup), so driving it low enables the switch; pin 5 is active high on TPS2150/51 instead. |
| 6 | LDO_EN | input | Active-high enable for the LDO regulator, with no internal pullup or pulldown. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | LDO_PG | output | LDO power-good output, open-drain and active high, indicating the LDO output status. |
| 9 | ADJ | input | Feedback adjustment input for the LDO that sets the output voltage (adjustable from 0.9 V to 3.3 V per the features list). |
| 10 | LDO_PLDN | input | LDO output pulldown pin; when connected to LDO_OUT it reduces the LDO output fall time without affecting rise time. |
| 11 | LDO_OUT | output | Output of the adjustable 250 mA LDO regulator. |
| 12 | SW_OUT | output | Output of the internal power-distribution switch; pins 12 and 13 are both SW_OUT. |
| 13 | SW_OUT | output | Second output pin of the power-distribution switch, connected in parallel with pin 12. |
| 14 | SW_PLDN | input | Switch output pulldown pin (open-drain discharge path, open when the switch is on and pulled to ground when off); connect to SW_OUT to reduce output fall time. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
