Not recommended for new designs – Please use MCP111/2 TC53 Voltage Detector Features: General Description: • • • • • • The TC53 is a low-power voltage detector. Typical supply current consumption is only 1A at an input voltage of 2V. The voltage detection threshold setting is factory-programmed and ensured to ±2% accuracy. Threshold settings are available over a range of 1.6V to 6.0V. 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. Highly Accurate: ±2% Low-Power Consumption: 1.0A, Typ. Detect Voltage Range: 1.6V to 6.0V and 7.7V 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 Functional Block Diagram 1) CMOS Output VIN Device Selection Table Part Number Package TC53-xxxxxxxxxx Temp.

The power consumption during power-start to output being stable (release operation) is 2A greater than it is after that period (completion of release operation) because of rush current in the delay circuit. VT is the factory-programmed voltage detection threshold. DS21432D-page 2  2001-2011 Microchip Technology Inc. TC53 2.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 2-1.
