Device Overview

Summary

The TC1031 is a low-power comparator and voltage reference designed specifically for low-power applications. The TC1031 is designed for operation from a single supply, however operation from dual supplies also is possible. The power supply current drain is independent of the magnitude of the power supply voltage. The TC1031 can operate from two 1.5V alkaline cells, and operation is guaranteed to VDD = 1.8V. Typical active supply current is 6 µA. Rail-to-rail inputs and outputs allow operation from low supply voltages with large input and output signal swings. The TC1031 provides a simple method for adding user-adjustable hysteresis without feedback or complex external circuitry. Hysteresis is adjusted with a simple resistor divider on the HYST input. A shutdown input, SHDN, disables the comparator and voltage reference and reduces supply current to less than 0.1 µA (maximum) when taken low. Packaged in a space-saving 8-Pin MSOP, the TC1031 is ideal for applications requiring high integration, small size and low power.
