The TLV803E, TLV809E, and TLV810E are enhanced alternatives to the TLV803, TLV853, TLV809, LM809, TPS3809 and TLV810. TLV803E, TLV809E and TLV810E offer lower supply current for battery-powered applications, higher accuracy, wider temperature range, and lower power-on-reset (VPOR) for increased system reliability.

The TLV803E, TLV809E, and TLV810E family are low IQ (250 nA typical, 1 µA max), voltage supervisory circuits (reset IC) that monitor VDD voltage level. These devices initiate a reset signal whenever supply voltage VDD drops below the factory programmed falling threshold voltage, VIT–. The reset output remains low for a fixed reset time delay tD 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 ideal for use in low-power and portable applications. The TLV80xE and TLV81xE devices are specified to have the defined output logic state for supply voltages down to VPOR = 0.7 V. The TLV80xE and TLV81xE devices are available in industry standard 3-pin SOT23 (DBZ) package, 3-pin SC70 (DCK) package, and very compact X2SON (DPW) package.
