# TLC7701QPWR

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

TLC7701QPWR 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 static-RAM power-down support; when tied to GND, RESET acts as active high, with input levels VIL max 0.2×VDD and VIH min 0.7×VDD. |
| 2 | RESIN | input | Reset input that, together with CONTROL and SENSE, determines the RESET and RESET output states per the function table, with VIL max 0.2×VDD and VIH min 0.7×VDD. |
| 3 | CT | passive | External timing capacitor connection that sets the reset delay time td = 2.1 × 10^4 × CT (CT in farads, td in seconds). |
| 4 | GND | power_in | Ground reference for the device; all voltage values are with respect to GND. |
| 5 | RESET | output | Active-low reset output (totem-pole), asserted when VDD reaches 1 V or SENSE is below threshold, rated for 2 mA high or low output current. |
| 6 | RESET | output | Active-high reset output (totem-pole) with 2 mA recommended output current, which is the complement of the active-low reset output. |
| 7 | SENSE | input | Voltage-sense input compared to the negative-going threshold (1.1 V typ for TLC7701, set by two external resistors), absolute maximum input range -0.3 to 7 V. |
| 8 | VDD | power_in | Supply voltage input, recommended operating range 2 V to 6 V with 7 V absolute maximum, and a 0.1 µF ceramic bypass capacitor recommended nearby. |
