TC54 Voltage Detector Features: General Description: 2.0% Detection Thresholds The TC54 series are CMOS voltage detectors espe- cially well-suited for battery-powered applications Small Packages: 3-Pin SOT-23A, SOT-89, and because of their extremely low 1 A operating current TO-92 and small surface-mount packaging. Each part is laser- Low Current Drain: 1 A, typical trimmed to the desired threshold voltage, which can be Wide Detection Range: 1.1V to 6.0V specified from 1.4V to 6.0V with a 2% tolerance. Wide Operating Voltage Range: 0.7V to 10V The TC54 is available with either an open-drain or com- plementary output stage. During operation, the output Applications: (V ) remains in the logic-high state as long as V is OUT IN greater than the specified threshold voltage (V ). Battery Voltage Monitoring DET When V falls below V , the output is driven to a IN DET Microprocessor Reset logic-low. V remains low until V rises above OUT IN System Brown-Out Protection V by an amount V , when it resets to a logic- DET HYST Switching Circuit in Battery Backup high state.
