TPS3305-33D from Texas Instruments, in a SOIC-8. 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 | SENSE1 | input | Sense voltage input 1; RESET is asserted when this input falls below its negative-going threshold VIT- (4.55 V typ for the TPS3305-33). |
| 2 | SENSE2 | input | Sense voltage input 2; RESET is asserted when this input falls below its negative-going threshold VIT- (2.93 V typ for the TPS3305-33). |
| 3 | WDI | input | Watchdog timer input; RESET is asserted if WDI is not toggled for more than the watchdog time-out (1.6 s typ). |
| 4 | GND | power_in | Ground; all voltage values in the datasheet are referenced to GND. |
| 5 | RESET | output | Active-low reset output; it goes low when a SENSEn input is below threshold, when MR is low, or on a watchdog time-out. |
| 6 | RESET | output | Active-high reset output, the complement of the active-low RESET on pin 5. |
| 7 | MR | input | Manual reset input; a low level asserts RESET (VIL = 0.3 x VDD max, VIH = 0.7 x VDD min), with a 100 ns minimum pulse width. |
| 8 | VDD | power_in | Supply voltage, specified from 2.7 V to 6 V (absolute maximum 7 V). |
