TC54  
VOLTAGE DETECTOR  
FEATURES  
GENERAL DESCRIPTION  
■ Precise Detection Thresholds .... Standard ± 2.0%  
Custom ± 1.0%  
■ Small Packages ........... SOT-23A-3, SOT-89, TO-92  
■ Low Current Drain ..................................... Typ. 1µA  
■ Wide Detection Range..........................2.1V to 6.0V  
■ Wide Operating Voltage Range ............ 1.5V to 10V  
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 2.1V to 6.0V,  
in 0.1V steps.  
The device includes a comparator, low-current high-  
precisionreference,laser-trimmeddivider,hysteresiscircuit  
andoutputdriver. TheTC54isavailablewitheitheranopen-  
drain or complementary output stage.  
APPLICATIONS  
■ Battery Voltage Monitoring  
■ Microprocessor Reset  
■ System Brownout Protection  
■ Switching Circuit in Battery Backup  
■ Level Discriminator  
In operation, the TC54's output (VOUT) remains in the  
logic HIGH state as long as VIN is greater than the  
specified threshold voltage (VD–ET). When VIN falls below  
V–DET, the output is driven to a logic LOW. VOUT remains  
LOW until VIN rises above V–DET by an amount VHYST  
whereupon it resets to a logic HIGH.
