TLV4011
SLVSFL9 –MARCH 2020
TLV4011 Precision Comparator with Integrated Reference
The factory-trimmed switching threshold and
precision hysteresis combine to make the TLV4011
appropriate for voltage and current monitoring in
harsh, noisy environments where slow moving input
signals must be converted into clean digital outputs.
Similarly, brief glitches on the input are rejected
thereby ensuring stable output operation without false
triggering.

Adjustable thresholds down to 1.226 V
Precision ±1.5% threshold voltage accuracy
Supply current: 3 μA
Open-drain output
Temperature range: –40°C to 85°C
5-Pin SC-70 package
During power on, RESET is asserted (LOW) when
the supply voltage VDD becomes higher than 0.8 V.
Thereafter, the TLV4011 monitors the input and
keeps RESET active (LOW) while the input remains
below the threshold voltage VIT. As soon as the input
rises above the threshold voltage VIT, RESET is de-
asserted (HIGH). The product spectrum is designed
for 1.8-V, 3.3-V, 5-V, and adjustable supply voltages.

3 Description
The TLV4011 is
and are characterized for operation over
temperature range of –40°C to 85°C.
a
a
low-power, high-accuracy
comparator with a precision, integrated reference.
Two external resistors can be connected to the input
to create an adjustable voltage threshold down to
1.226 V.
