3 Description

The TLV803E,TLV809E, and TLV810E are enhancedalternatives to the TLV803,TLV853,TLV809,LM809,TPS3809 and TLV810.TLV80xE and TLV81xE offerlow quiescent current la,higher accuracy,widertemperature range, and lower power-on-reset (VPOR)for increased system reliability.

The TLV80xE and TLV81xE family are low lo (250 nAtypical,1 μA max),voltage supervisory circuits(resetIC)that monitor VDD voltage level. These devicesinitiate a reset signal whenever supply voltage VDDdrops below the factory programmed falling thresholdvoltage,V+_. The reset output remains low for a fixedreset time delay tp after the VDD voltage rises abovethe rising voltage threshold (V++) which is equivalentto the falling threshold voltage (V+.) plus hysteresis(VHYs).

These devices have integrated glitch immunity toignore fast transients on the DD pin.The lowlo and high accuracy(+0.5% typical)makes thesevoltage supervisors ideal for use in low-power andportable applications.The TLV80xE and TLV81xEdevices are specified to have the defined output logicstate for supplyvoltages downtoVpoR =0.7 V.The TLV80xE and TLV81xE devices are availablein industry standard 3-pin SOT23(DBZ)and SC70(DCK)packages and very compact X2SON(DPW)package.
