Texas Instruments · Monitors & Reset Circuits · SO-8-208mil

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.
