TLV40x1 Small-Size, Low-Power Comparator with Precision Reference

1 Features

3 Description

The TLV40x1 devices are low-power, high-accuracy

comparators with precision references and fast

response. The comparators are available in an ultra-

small, DSBGA package measuring 0.73 mm × 0.73

mm, making the TLV40x1 applicable for space-critical

designs like portable or battery-powered electronics

where low-power and fast response to changes in

operating conditions is required.

•

Wide supply voltage range: 1.6 V to 5.5 V

Precision References: 0.2 V, 0.5 V, and 1.2 V

Fixed threshold of 3.2 V

•

Reference accuracy

–

0.5% at 25°C

1% over temperature

•

Low quiescent current: 2 µA

Propagation delay: 360 ns

Push-pull and open-drain output options

Known startup conditions

The factory-trimmed references and precision

hysteresis combine to make the TLV40x1 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 ensuring stable

output operation without false triggering.

Non-inverting and inverting input options

Precision hysteresis

Temperature range: –40°C to +125°C

Packages:

The TLV40x1 are available in multiple configurations

allowing system designers to achieve their desired

output response. For example, the TLV4021 and

–

0.73 mm × 0.73 mm DSBGA (4-bump)

SOT-23 (5-pin)

TLV4041 offer

a non-inverting input, while the

TLV4031 and TLV4051 have an inverting input.

Furthermore, the TLV4021 and TLV4031 feature an

open-drain output stage, while the TLV4041 and

TLV4051 feature a push-pull output stage. Lastly,

each comparator in the TLV40x1 family is available

with a 0.2V, 0.5V, or 1.2V precision reference.
