TPS3307-18DGNR from Texas Instruments, in a MSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SENSE1 | input | Sense voltage input 1 for monitoring 3.3V supply with threshold voltage 2.93V. |
| 2 | SENSE2 | input | Sense voltage input 2 for monitoring 1.8V supply with threshold voltage 1.68V. |
| 3 | SENSE3 | input | Sense voltage input 3 for user-defined supply monitoring with 1.25V nominal threshold voltage. |
| 4 | GND | power_in | Ground reference. |
| 5 | RESET | output | Active-low reset output asserted low when supply voltage or sense input falls below threshold. |
| 6 | RESET | output | Active-high reset output providing logical complement of pin 5. |
| 7 | MR | input | Manual reset input (active-low); pulling low forces RESET assertion regardless of supply voltage state. |
| 8 | VDD | power_in | Supply voltage input; operating range 2V to 6V with RESET asserted when VDD falls below 1.1V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
