TLV809EA45DBZR

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

TLV809EA45DBZR 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 reference for all internal circuitry; VDD is specified -0.3 V to 6.5 V relative to this pin.
2 RESET output Active-low push-pull reset output (TLV809E); driven low when VDD falls below VIT- (4.55 V for this variant) after propagation delay tPD_HL (30-50 µs typ); held asserted for reset delay tD (200 ms typ, 130-270 ms range) after VDD rises above VIT+; VOL ≤ 300 mV at IOUT(sink) = 2 mA, VOH ≥ 0.8×VDD at IOUT(source) = 2 mA; output current limit ±5 mA recommended.
3 VDD power_in Input supply voltage monitored by internal comparator against fixed falling threshold VIT- = 4.55 V; operating range 1.7 V to 6 V; IDD = 250 nA typ / 1 µA max at VDD = 3.3 V; 0.1 µF to 1 µF bypass capacitor recommended.
