DESCRIPTION
The TSM917 nanopower analog parator is electrically and form-factor identical to the MAX917 analog parator. Ideally suited for all 2-cell batterymanagement/monitoring applications, this 5-pin SOT23 analog parator 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 750n A of supply current and includes an on-board 1.245V ±1.5% reference. The TSM917’s push-push output drivers were designed to drive 8m A loads from one supply rail to the other supply rail. The TSM917 is also available in an 8-pin SOIC package.
