Description

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

The TLV8xxE family are low current (250 nA typical, 2 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 threshold voltage, VIT–. The reset output remains low for a fixed reset time delay tD after the VDD voltage rises above the threshold voltage and hysteresis.

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