Voltage Detector  
Features  
General Description  
• Precise Detection Thresholds: Standard ±2.0%,  
Custom ±1.0%  
The TC54 Series are CMOS voltage detectors, suited  
especially for battery-powered applications because of  
their extremely low 1µA operating current and small  
surface-mount packaging. Each part is laser trimmed to  
the desired threshold voltage which can be specified  
from 1.1V to 6.0V and 7.7V, for a 2% and 1.5V to 6.0V  
for a 1% tolerance.  
• Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89,  
5-Pin SOT-23A (7.7V only)  
• Low Current Drain: Typ. 1µA  
• Wide Detection Range: 1.1V to 6.0V and 7.7V  
• Wide Operating Voltage Range: 0.7V to 10V  
The device includes a comparator, low-current high-  
precision reference, laser-trimmed divider, hysteresis  
circuit and output driver. The TC54 is available with  
either an open-drain or complementary output stage.  
Applications  
• Battery Voltage Monitoring  
• Microprocessor Reset  
In operation, the TC54's output (VOUT) remains in the  
logic HIGH state as long as VIN is greater than the  
specified threshold voltage (VDET-). When VIN falls  
below VDET - the output is driven to a logic LOW. VOUT  
remains LOW until VIN rises above VDET - by an  
amount VHYST, whereupon it resets to a logic HIGH.  
• System Brown-out Protection  
• Switching Circuit in Battery Backup  
• Level Discriminator
