TSM9117-TSM9120

1.6V Nanopower Comparators with/without Internal References

DESCRIPTION

FEATURES

♦ Second-source for MAX9117-MAX9120

♦ Guaranteed to Operate Down to +1.6V

♦ Ultra-Low Supply Current

The TSM9117–TSM9120 family of nanopower

comparators is electrically and form-factor identical to

the

MAX9117-MAX9120

family

analog

350nA - TSM9119/TSM9120

600nA - TSM9117/TSM9118

comparators. Ideally suited for all 2-cell battery-

management/monitoring applications, these 5-pin

SC70 analog comparators guarantee +1.6V

operation, draw very little supply current, and have

robust input stages that can tolerate input voltages

beyond the power supply. The TSM9117 and the

TSM9118 draw 600nA of supply current and include

an on-board 1.252V ±1.75% reference. The

comparator-only TSM9119 and the TSM9120 draw a

supply current of 350nA.

♦ Internal 1.252V ±1.75% Reference

♦ Input Voltage Range Extends 200mV Outside-the-Rails

♦ No Phase Reversal for Overdriven Inputs

♦ Push-pull and Open-Drain Output Versions Available

♦ Crowbar-Current-Free Switching

♦ Internal Hysteresis for Clean Switching

♦ 5-pin SC70 and 8-pin SOIC Packaging

APPLICATIONS

2-Cell Battery Monitoring/Management

Medical Instruments

Threshold Detectors/Discriminators

Sensing at Ground or Supply Line

Ultra-Low-Power Systems

The TSM9117 and TSM9119’s push-push output

drivers were designed to drive 5mA loads from one

supply rail to the other supply rail. The TSM9118 and

the TSM9120’s open-drain output stages make it

easy to incorporate these comparators into systems

that operate on different supply voltages.
