3 Description

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.
