TSM917

www.DataSheet4U.net TSM917 1.8V Nanopower Comparator with Internal 1.245V Reference FEATURES ♦ Second-source for MAX917 ♦ Guaranteed to Operate Down to +1.8V ♦ Ultra-Low Supply Current: 750nA ♦ Internal 1.245V ±1.5% Reference ♦ Input Voltage Range Extends 200mV Outside-the-Rails ♦ No Phase Reversal for Overdriven Inputs ♦ Push-pull Output ♦ Crowbar-Current-Free Switching ♦ Internal Hysteresis for Clean Switching ♦ 5-pin SOT23 and 8-pin SOIC Packaging DESCRIPTION The TSM917 nanopower analog comparator is electrically and form-factor identical to the MAX917 analog comparator. Ideally suited for all 2-cell batterymanagement/monitoring applications, this 5-pin SOT23 analog comparator guarantees +1.8V operation, draws very little supply current, and has a robust input stage that can tolerate input voltages beyond its power supply. The TSM917 draws 750nA of supply current and includes an on-board 1.245V ±1.5% reference. The TSM917’s push-push output drivers were designed to drive 8mA loads from one supply rail to the other supply rail. The TSM917 is also available in an 8-pin SOIC package.
