TL7733BIDR from Texas Instruments, in a SOIC-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 | REF | output | Reference voltage output with nominal value 2.53 V and range 2.48-2.58 V at 25°C; connect 0.1-µF decoupling capacitor to GND. |
| 2 | RESIN | input | Reset input; when low, overrides monitoring and forces RESET high; when high, enables voltage monitoring; input range 0-18 V. |
| 3 | CT | output | Timing capacitor input; charges via internal current source to determine reset pulse duration using formula td ≈ 2.6×10⁴×CT(seconds). |
| 4 | GND | power_in | Ground reference. |
| 5 | RESET | output | Active-low open-collector reset output; actively driven low upon undervoltage detection or when RESIN input is low; output sinks up to 20 mA. |
| 6 | RESET | output | Active-high open-collector reset output; actively driven high upon undervoltage detection or when RESIN input is low; output sources up to 20 mA. |
| 7 | SENSE | input | Voltage sense input; monitors supply voltage and triggers reset outputs when voltage falls below negative-going threshold of 3.0-3.16 V for TL7733B; input range 0-18 V. |
| 8 | VCC | power_in | Supply voltage input; operating range 3.6-18 V; connect 0.1-µF decoupling capacitor to GND. |
