TC1031 pdf datasheet

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 is
also 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 ensured to VDD = 1.8V.
Typical active supply current is 6μA. 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 useradjustable
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 0.1μA
(maximum) when taken low.
The TC1031 is packaged in a space-saving 8-Pin
MSOP, making it ideal for applications requiring high
integration, small size and low power.
