TL7700CPS from Texas Instruments, in a SO-8-208mil. 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 | CT | bidirectional | Timing capacitor connection that sets the RESET output pulse duration (tpo = Ct × 10^5 s) through an internal 15-µA constant-current source, and no external voltage may be applied to it, so it must be driven only by an open-collector transistor, FET, or 3-state buffer. |
| 2 | SENSE | input | Voltage sense input with a 500 mV typical threshold (±1.0% at 25°C) that is set above 0.5 V with two external resistors, which also set the hysteresis, and it has a -0.3 V to 41 V input range. |
| 3 | NC | unconnected | No internal connection. |
| 4 | GND | power_in | Ground reference for the device, which should be kept as low impedance as possible to reduce circuit noise. |
| 5 | VCC | power_in | Power supply input for the 1.8 V to 40 V operating range, with a 41 V absolute maximum. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | RESET | output | Active-low reset output implemented as an npn open-collector transistor that requires a pullup resistor, with a recommended low-level output current of 3 mA maximum (5 mA absolute maximum) and an off-state output voltage of 41 V maximum. |
