# TL7702BIP

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

TL7702BIP from Texas Instruments, in a PDIP-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 | Reference voltage output (VREF 2.48 V to 2.58 V at Iref = -500 µA, 25°C); a 0.1-µF decoupling capacitor on REF is recommended to reduce false triggering from noise. |
| 2 | RESIN | input | Reset input: when driven low, RESET goes high and ~{RESET} goes low; when high, the reset outputs respond to the SENSE voltage. VIH is 2 V to 18 V and VIL is 0 V to 0.8 V. |
| 3 | CT | passive | Timing capacitor connection that sets the reset pulse duration, td ≈ 2.6 × 10^4 × CT (CT in farads, td in seconds), counted from the moment SENSE exceeds the positive-going threshold. |
| 4 | GND | power_in | Ground reference; all device voltages are referenced to the network ground terminal. |
| 5 | ~{RESET} | output | Active-low reset output, open-collector, requiring a pullup resistor; recommended IOL is 20 mA maximum (absolute maximum 30 mA). |
| 6 | RESET | output | Active-high reset output, open-collector, requiring a pullup resistor; recommended IOH is -20 mA (absolute maximum -30 mA), and both outputs should be terminated with similar-value resistors. |
| 7 | SENSE | input | Undervoltage-monitored voltage input rated 0 V to 18 V; for the TL7702B the negative-going threshold VIT- is typically 2.53 V (2.48 V to 2.58 V over full temperature range) and hysteresis is typically 10 mV. |
| 8 | VCC | power_in | Supply voltage, recommended 3.6 V to 18 V (absolute maximum 20 V). |
