Pinout
1. VCC (Pin 1): Supply voltage input.
2. SENSE (Pin 2): Input for sensing the monitored voltage.
3. GND (Pin 3): Ground connection.
4. RESET (Pin 4): Output for reset signal; goes low when the monitored voltage is below the threshold.
5. NC (Pin 5): No connection; not internally connected.
6. NC (Pin 6): No connection; not internally connected.
7. NC (Pin 7): No connection; not internally connected.
8. NC (Pin 8): No connection; not internally connected.
The TL7700 ensures that the RESET signal is activated when the sensed voltage drops below a specified threshold, which helps in the reliable power-up and power-down of digital systems.
