# TL7712AIDR

**Texas Instruments** · Supervisor And Reset ICs · SOIC-8

TL7712AIDR 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 | REF | output | Voltage reference output of the supervisor; the datasheet gives no electrical limit for this pin. |
| 2 | RESIN | input | Reset input; recommended VIH is 2 V minimum and VIL is 0.6 V maximum. |
| 3 | CT | bidirectional | External timing-capacitor pin that sets the reset delay time; the datasheet gives no voltage limit for this pin. |
| 4 | GND | power_in | Device ground; all voltages in the datasheet are referenced to GND. |
| 5 | RESET | output | Inverted supervisor reset output (active high when RESET is low); recommended IOL/IOH is ±16 mA and absolute maximum is ±30 mA. |
| 6 | RESET | output | Supervisor reset output that goes active (low) on power-up below the threshold and on undervoltage at SENSE; recommended IOH is -16 mA and IOL is 16 mA, absolute maximum ±30 mA. |
| 7 | SENSE | input | Undervoltage sense input; for the TL7712A the recommended input voltage range is 0 V to 20 V and the absolute maximum range is -0.3 V to 20 V. |
| 8 | VCC | power_in | Supply voltage pin; recommended supply range is 3.5 V to 18 V and absolute maximum is 20 V. |
