General Description
The TC54 series are CMOS voltage detectors that are especially well suited for battery-powered applications because of their extremely low 1 µA operating current and small surface-mount packaging. Each part is lasertrimmed to the desired threshold voltage, which can be specified from 1.4V to 6.0V with a 2% tolerance.

FEATUREs
• ±2.0% Detection Thresholds
• Small Packages: 3-Pin SOT-23A, SOT-89, and TO-92
• Low Current Drain: 1 µA, typical
• Wide Detection Range: 1.1V to 6.0V
• Wide Operating Voltage Range: 0.7V to 10V

APPLICATIONs
• Battery Voltage Monitoring
• Microprocessor Reset
• System Brown-Out Protection
• Switching Circuit in Battery Backup
• Level Discriminator
