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 7.7V for a 2% tolerance and from 1.5V to 6.0V for a 1% tolerance.

FEATUREs
• Precise Detection Thresholds: Standard ±2.0%, Custom ±1.0%
• Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89, TO-92 and 5-Pin SOT-23A (7.7V only)
• Low Current Drain: Typ. 1 µA
• Wide Detection Range: 1.1V to 6.0V and 7.7V
• 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
