Overview
TSM9117-TSM9120 1.
6V Nanopower Comparators with/without Internal References FEATURES ♦ Second-source for MAX9117-MAX9120 ♦ Guaranteed to Operate Down to +1.
6V ♦ Ultra-Low Supply Current 350nA - TSM9119/TSM9120 600nA - TSM9117/TSM9118 ♦ 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 DESCRIPTION The TSM9117–TSM9120 family of nanopower comparators is electrically and form-factor identical to the MAX9117-MAX9120 family of analog comparators.
Ideally suited for all 2-cell batterymanagement/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.
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.
