Detect Voltage Range ... 1.6V to 6.0V in 0.1V Steps Operating Voltage ............................... 1.5V to 10.0V Output Configuration ........... Open Drain or CMOS Space-Saving .................. 5-Pin SOT-23A Package, TYPICAL APPLICATIONS Microprocessor Reset Circuits Battery Life Monitors and Recharge Voltage Monitors Memory Battery Backup Circuitry Power-On Reset Circuits Power Failure Detection Delay Circuitry The TC53 is a low power voltage detector. Typical supply current consumption is only 1A at an input voltage of 2V. The voltage detection threshold setting is factoryprogrammed and guaranteed to 2% accuracy. Threshold settings are available over a range of 1.6V to 6.0V in 100mV steps. The TC53 has both complementary (CMOS) and open drain (NMOS) output configuration options. TC53 is the ideal voltage detector for precision applications in which small size, low installed cost, high accuracy, and low supply current consumption are critical.

An additional resistor between the VIN pin and the supply voltage may cause alterations in the characteristics due to the increasing values of VDR. 2. The power consumption during power-start to output being stable (release operation) is 2A greater than it is after that period (completion of release operation) because of rush current in the delay circuit. 3. VT is the factory-programmed voltage detection threshold.
