1 - 12 V | LTCxxxx series
Supervisory circuits with linear technology monitor power supply and voltage. These will monitor both negative and positive power supplies and offer integration of up to eight supply monitors in a small unit. The reset signal is generated when the power goes above or below the established threshold. These reset times are fixed at 200ms however, this can be adjusted with a single capacitor.
ASICs and CPUs can also benefit from this integrated watch dog timer. LTC2934 and LTC2935 nano current supervisors work well with portable applications and LTC2960 shigh voltage monitors will monitor voltages up to 36V.
