Texas Instruments · Supervisor And Reset ICs · MSOP-8
TPS3705-50DGN from Texas Instruments, in a MSOP-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 | RESET | output | Active-low reset output that goes low at power-up once VDD exceeds 1.1 V and again whenever VDD falls below the threshold VIT-. |
| 2 | WDO | output | Watchdog timer output, used by the TPS3705-xx integrated watchdog function. |
| 3 | MR | input | Manual reset input; the datasheet specifies VIH of at least 0.7 × VDD, VIL of at most 0.3 × VDD, and an input rise/fall rate of at most 100 ns/V for MR or WDI. |
| 4 | VDD | power_in | Supply voltage, recommended range 2 V to 6 V, with an absolute maximum of 7 V referenced to GND. |
| 5 | GND | power_in | Ground reference; all voltage values in the datasheet are specified with respect to GND. |
| 6 | PFI | input | Power-fail comparator input, with a voltage range of -0.3 V to VDD + 0.3 V. |
| 7 | PFO | output | Power-fail comparator output that signals a power-fail or low-battery warning. |
| 8 | WDI | input | Watchdog timer input; the datasheet specifies VIH of at least 0.7 × VDD, VIL of at most 0.3 × VDD, and an input rise/fall rate of at most 100 ns/V for WDI. |
