General Description

The MAX40000/MAX40001 are tiny, single comparators

with built-in voltage references that are ideal for a wide

variety of portable electronics applications, such as cell

phones, portable instruments, and notebooks that have

extremely tight board space and power constraints. The

MAX40000/MAX40001 are available in a 6-bump wafer-

level package (WLP) with 1.11mm x 0.76mm footprint and

a 6-pin SOT23 package. The MAX40000 has a push-pull

output and the MAX40001 has an open-drain output.

The devices offer a supply voltage range from 1.7V to

5.5V and consume only 0.9μA of supply current. They also

feature internal filtering to provide high RF immunity, im-

portant in many portable applications.

The devices have a high-precision integrated reference

that is factory trimmed to an initial accuracy of 1% and bet-

ter than 2.5% over the entire temperature range. Internal

reference voltage options include 1.252V, 1.66V, 1.94V,

and 2.22V. See Ordering Information for help with order-

ing a MAX40000/MAX40001 with a particular voltage ref-

erence value and package type. The reference output is

stable for capacitive loads up to 100pF.

These devices are fully specified over -40°C to +125°C

automotive temperature range.

Preserves Battery Power

● Tiny 1.11mm x 0.76mm 6-Bump WLP and SOT23

Packages Save Board Space

● Internal Precision Reference Saves Space and Cost

of an External Reference

• < 1% at Room Temperature, < 2.5% Over Temp

Reference

• Multiple Reference Voltages (1.252V, 1.66V, 1.94V,

and 2.22V)

● Input Voltage Range = -0.2V to 5.7V

● Supply Voltage Range (1.7V to 5.5V) Allows

Operation from 1.8V, 2.5V, 3V, and 5V Supplies

● <10μs Propagation Delay

● Push-Pull (MAX40000) or Open-Drain (MAX40001)
