TC54  
Voltage Detector  
Features  
General Description  
• ±2.0% Detection Thresholds  
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 laser-  
trimmed to the desired threshold voltage, which can be  
specified from 1.4V to 6.0V with a 2% tolerance.  
• Small Packages: 3-Pin SOT-23A, 3-Pin 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  
The TC54 is available with either an open-drain or com-  
plementary output stage. During operation, the TC54's  
output (VOUT) remains in the logic-high state as long as  
VIN is greater than the specified threshold voltage  
Applications  
• Battery Voltage Monitoring  
• Microprocessor Reset  
(VDET ). When VIN falls below VDET , the output is  
driven to a logic-low. VOUT remains low until VIN rises  
• System Brown-Out Protection  
• Switching Circuit in Battery Backup  
• Level Discriminator  
above VDET by an amount VHYST, whereupon it  
resets to a logic-high.
