## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | output | Voltage reference output from the temperature-compensated reference; no output voltage or current limit for this pin is stated in the provided text. |
| 2 | RESIN | input | Reset input with a high-level input voltage of at least 2 V and a low-level input voltage of at most 0.6 V, and an absolute maximum input voltage range of -0.3 V to 20 V. |
| 3 | CT | bidirectional | External timing-capacitor pin that sets the adjustable reset pulse duration; no capacitor value or voltage limit is stated in the provided text. |
| 4 | GND | power_in | Device ground, to which all voltage values in the datasheet are referenced. |
| 5 | RESET | output | Inverted supervisor reset output that goes active when an undervoltage condition occurs; recommended output current is -16 mA (IOH) to 16 mA (IOL), with absolute maximum output current of ±30 mA. |
| 6 | RESET | output | Supervisor reset signal output that goes active when an undervoltage condition occurs; recommended output current is -16 mA (IOH) to 16 mA (IOL), with absolute maximum output current of -30 mA (IOH) to 30 mA (IOL). |
| 7 | SENSE | input | Undervoltage sense input; for the TL7709A the recommended input voltage is 0 V to 15 V and the absolute maximum range is -0.3 V to 20 V. |
| 8 | VCC | power_in | Power supply input with a recommended supply voltage of 3.5 V to 18 V and an absolute maximum of 20 V. |
