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.

1 Features

•

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 V_DDbecomes higher than 0.8 V.

Thereafter, the TLV4011 monitors the input and

keeps RESET active (LOW) while the input remains

below the threshold voltage V_IT. As soon as the input

rises above the threshold voltage V_IT, RESET is de-

asserted (HIGH). The product spectrum is designed

for 1.8-V, 3.3-V, 5-V, and adjustable supply voltages.

2 Applications

•

Electricity meters

Circuit breakers

Thermostats

Cordless power tools

The TLV4011 is available in a 5-pin SC-70 package

3 Description

The TLV4011 is

and are characterized for operation over

temperature range of –40°C to 85°C.

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.
