TL7700CPW

Texas Instruments · Monitors & Reset Circuits · TSSOP-8

TL7700CPW from Texas Instruments, in a TSSOP-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 CT bidirectional Timing-capacitor connection that sets the RESET output pulse duration (tpo) through an internal 15-µA constant-current source; no external voltage may be applied, so drive it with an open-collector transistor, FET, or 3-state buffer.
2 SENSE input Voltage-sense input with a 500 mV typical threshold, temperature compensated, where two external resistors set the sense voltage and hysteresis.
3 NC unconnected No internal connection.
4 GND power_in Ground; keep this terminal as low impedance as possible to reduce circuit noise.
5 VCC power_in Power supply input, specified for an operating voltage range of 1.8 V to 40 V.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 RESET output Active-low reset output that is an NPN open-collector transistor and requires a pullup resistor; an additional transistor is needed for active-high reset or higher output current.

CAD (KiCad official)

  • Symbol: TL7700CPW
  • Footprint: Package_SO:TSSOP-8_3x3mm_P0.65mm
  • 3D model: TSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: tl7700cpw-etched.step / tl7700cpw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl7700cpw.step / tl7700cpw.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
