# TLV809EA43DBZR

**Texas Instruments** · Supervisor And Reset ICs · SOT-23-3

TLV809EA43DBZR from Texas Instruments, in a SOT-23-3. 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 | GND | power_in | Ground pin; for the standard DBZ pinout with no R or V indicator in the part number (TLV809EA43DBZR), pin 1 is GND. |
| 2 | RESET | output | Push-pull active-low reset output that is driven low when VDD falls below VIT- and stays low for the delay time tD after VDD rises above VIT+, with recommended pin current of 0 to ±5 mA. |
| 3 | VDD | power_in | Input supply voltage monitored by the supervisor, with a recommended range of 1.7 V to 6 V and an absolute maximum of 6.5 V. |
