The TLV803E/TLV809E are enhanced alternatives to the TLV803, TLV853, TLV809, LM809, andTPS3809. TLV803E and TLV809E offer lower supply current for battery-powered applications, higheraccuracy, wider temperature range, and lower power-on reset (VPOR) forincreased system reliability.

The TLV8xxE family are low IQ (250 nA typical, 1 µA max), voltagesupervisory circuits (reset IC) that monitor VDD voltage level. These devices initiate a resetsignal whenever supply voltage VDD drops below the factory programmed falling threshold voltage,VIT–. The reset output remains low for a fixed reset time delaytD after the VDD voltage rises above the rising voltage threshold(VIT+) which is equivalent to the falling threshold voltage(VIT-) plus hysteresis (VHYS).

These devices have integrated glitch immunity to ignore fast transients on the VDD pin.The low current consumption and high accuracy (±0.5% typical) makes these voltage supervisors idealfor use in low-power and portable applications. The TLV8xxE devices are specified to have thedefined output logic state for supply voltages down to VPOR = 0.7 V. TheTLV8xxE devices are available in industry standard 3-pin SOT23 (DBZ) package and 3-pin, SC70 (DCK)package.
