The TLV803E, TLV809E, and TLV810E are enhanced alternatives to the TLV803, TLV853, TLV809, LM809, TPS3809 and TLV810. TLV80xE and TLV81xE offer low quiescent current IQ, higher accuracy, wider temperature range, and lower power-on-reset (VPOR) for increased system reliability.

The TLV80xE and TLV81xE 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 IQ 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) and SC70 (DCK) packages and very compact X2SON (DPW) package.
