# TLC7733IPWR

**Texas Instruments** · Monitors & Reset Circuits · TSSOP-8

TLC7733IPWR 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 | CONTROL | input | Control input for RAM battery-backup support; when tied to GND, RESET acts as active high, with VIL below 0.2×VDD and VIH above 0.7×VDD. |
| 2 | RESIN | input | Active-low reset input (overline RESIN) that forces the reset outputs active, with VIL below 0.2×VDD and VIH above 0.7×VDD. |
| 3 | CT | passive | Connection for the external delay capacitor that sets the delay time td = 2.1 × 10^4 × CT (CT in farads, td in seconds). |
| 4 | GND | power_in | Ground reference for the supply and all voltages. |
| 5 | RESET | output | Active-low totem-pole reset output (overline RESET), driven low while SENSE is below threshold and during the delay time td. |
| 6 | RESET | output | Active-high totem-pole reset output, rated for 2 mA output current, which becomes active when SENSE drops below threshold. |
| 7 | SENSE | input | Voltage monitor input compared against the 2.93 V typical negative-going threshold (TLC7733), with 70 mV hysteresis. |
| 8 | VDD | power_in | Supply voltage input, 2 V to 6 V recommended with 7 V absolute maximum; RESET is defined from VDD of 1 V. |
