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.
