# TL7702ACDR

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

TL7702ACDR 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. |
| 2 | RESIN | input | Reset input, which requires a high-level input voltage of at least 2 V (VIH) and a low-level input voltage of at most 0.6 V (VIL). |
| 3 | CT | bidirectional | External timing-capacitor pin that sets the time delay of the delay timer. |
| 4 | GND | power_in | Device ground; all voltage values in the datasheet are with respect to GND. |
| 5 | RESET | output | Inverted supervisor reset signal output, the complement of RESET (pin 6). |
| 6 | RESET | output | Supervisor reset signal output, which goes active (low) on power-up or undervoltage; recommended output current is -16 mA (IOH) to 16 mA (IOL). |
| 7 | SENSE | input | Undervoltage sense input; for the TL7702A the voltage applied must not exceed VCC − 1 V or 6 V, whichever is less. |
| 8 | VCC | power_in | Power supply input with a recommended range of 3.5 V to 18 V and an absolute maximum of 20 V. |
