SOT23, 1.8V, Nanopower, Beyond-the-Rails

Comparators With/Without Reference

17–MAX920

General Description

Features

The MAX917–MAX920 nanopower comparators in

space-saving SOT23 packages feature Beyond-the-

Rails™ inputs and are guaranteed to operate down to

+1.8V. The MAX917/MAX918 feature an on-board

1.245V 1.5ꢀ reference and draw an ultra-low supply

current of only 750nA, while the MAX919/MAX920 (with-

out reference) require just 380nA of supply current.

These features make the MAX917–MAX920 family of

comparators ideal for all 2-cell battery applications,

including monitoring/management.

♦ Ultra-Low Supply Current

380nA per Comparator (MAX919/MAX920)

750nA per Comparator with Reference

(MAX917/MAX918)

♦ Guaranteed to Operate Down to +1.8V

♦ Internal 1.245V ±1.5% Reference

(MAX917/MAX918)

♦ Input Voltage Range Extends 200mV

Beyond-the-Rails

The unique design of the output stage limits supply-cur-

rent surges while switching, virtually eliminating the

supply glitches typical of many other comparators. This

design also minimizes overall power consumption

under dynamic conditions. The MAX917/MAX919 have

a push/pull output stage that sinks and sources current.

Large internal output drivers allow Rail-to-Rail^®output

swing with loads up to 8mA. The MAX918/MAX920

have an open-drain output stage that makes them suit-

able for mixed-voltage system design.

♦ CMOS Push/Pull Output with ±8mA Drive

Capability (MAX917/MAX919)

♦ Open-Drain Output Versions Available

(MAX918/MAX920)

♦ Crowbar-Current-Free Switching

♦ Internal Hysteresis for Clean Switching

♦ No Phase Reversal for Overdriven Inputs

♦ Space-Saving SOT23 Package
