3 Description
•
•
Ensured RESET/RESET for VDD = 0.7 V to 6 V
Fixed time delay: 40 µs, 10 ms, 50 ms, 100 ms,
200 ms, 400 ms
Supply current (IDD): 250 nA (typical)
– 1 µA (maximum for VDD = 3.3 V)
Output topology:
The TLV803E, TLV809E, and TLV810E are enhanced
alternatives to the TLV803, TLV853, TLV809, LM809,
TPS3809 and TLV810. TLV80xE and TLV81xE offer
low quiescent current I Q, 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).
– TLV809E: push-pull, active-low
– TLV803E: open-drain, active-low
– TLV810E: push-pull, active-high
Under voltage detection:
– High accuracy: ±0.5% (typical)
– (VIT–): 1.7 V, 1.8 V, 1.9 V, 2.25V, 2.4 V, 2.64 V,
2.93 V, 3.08ꢀV, 3.3V, 4.2V, 4.38 V, 4.55V, 4.63 V
Package:
– SOT23-3 (DBZ) (with pin 1 = GND)
– SOT23-3 (DBZ) (with pin 1 = RESET/RESET)
– SOT23-3 (DBZ) (with pin 3 = GND)
– SC-70 (DCK)

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.
