TL7700CDGKR from Texas Instruments, in a VSSOP-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 | RESET | output | Active-low reset output that is an NPN open-collector transistor and requires a pullup resistor, with an additional transistor needed for active-high reset or higher output current. |
| 2 | NC | unconnected | No internal connection. |
| 3 | CT | bidirectional | Timing capacitor connection that sets the RESET pulse duration (tpo) through an internal 15 µA constant-current source, and must not have an external voltage applied, so it should be driven by an open-collector transistor, FET, or 3-state buffer. |
| 4 | SENSE | input | Voltage sense input with a 500 mV threshold, where two external resistors set the sense voltage and hysteresis. |
| 5 | GND | power_in | Ground; keep this terminal as low impedance as possible to reduce circuit noise. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | VCC | power_in | Power supply input for an operating voltage range of 1.8 V to 40 V. |
