2001-2014 Microchip Technology 1TC54 Features: Detection Thresholds Small Packages: 3-Pin SOT-23A, SOT-89, and TO-92 Low Current Drain: 1 A, typical Wide Detection Range: to Wide Operating Voltage Range: to 10 VApplications: Battery Voltage Monitoring Microprocessor Reset System Brown-Out Protection Switching Circuit in Battery Backup Level DiscriminatorFunctional Block DiagramGeneral Description:The tc54 series are CMOS voltage detectors espe-cially well-suited for battery-powered applicationsbecause of their extremely low 1 A operating currentand small surface-mount packaging. Each part is laser-trimmed to the desired threshold voltage, which can bespecified from to with a 2% tc54 is available with either an open-drain or com-plementary output stage.
