MAX40000/MAX40001 1.7V, nanoPower Comparators with Built-In Reference General Description Benefits and Features The MAX40000/MAX40001 are tiny, single comparators Micropower Operating Current (0.9A typ, 1.7A max) with built-in voltage references that are ideal for a wide Preserves Battery Power variety of portable electronics applications, such as cell Tiny 1.11mm x 0.76mm 6-Bump WLP and SOT23 phones, portable instruments, and notebooks that have Packages Save Board Space extremely tight board space and power constraints. The Internal Precision Reference Saves Space and Cost MAX40000/MAX40001 are available in a 6-bump wafer- of an External Reference level package (WLP) with 1.11mm x 0.76mm footprint and < 1% at Room Temperature, < 2.5% Over Temp a 6-pin SOT23 package. The MAX40000 has a push-pull Reference output and the MAX40001 has an open-drain output. Multiple Reference Voltages (1.252V, 1.66V, 1.94V, and 2.22V) The devices offer a supply voltage range from 1.7V to 5.5V and consume only 0.9A of supply current. They also Input Voltage Range = -0.2V to 5.7V feature internal filtering to provide high RF immunity, im- Supply Voltage Range (1.7V to 5.5V) Allows portant in many portable applications. Operation from 1.8V, 2.5V, 3V, and 5V Supplies <10s Propagation Delay The devices have a high-precision integrated reference Push-Pull (MAX40000) or Open-Drain (MAX40001) that is factory trimmed to an initial accuracy of 1% and bet- Outputs ter than 2.5% over the entire temperature range.
