Linear Building Block – Low Power Voltage Reference with

Programmable Hysteresis Comparator and Shutdown

Features

General Description

• Combines Comparator and Voltage Reference in

a Single Package

The TC1031 is a low-power comparator and voltage

reference designed specifically for low-power applica-

tions. 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 V_DD= 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.

• Optimized for Single Supply Operation

• Small Package: 8-Pin MSOP

• Ultra Low Input Bias Current: Less than 100pA

• Low Quiescent Current, Active: 6μA (Typ.),

Shutdown Mode: 0.1μA (Typ.)

• Rail-to-Rail Inputs and Outputs

• Operates Down to V_DD= 1.8V

• Programmable Hysteresis

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 0.1μA

(maximum) when taken low.

Applications

• Power Management Circuits

• Battery Operated Equipment

• Consumer Products

Device Selection Table

The TC1031 is packaged in a space-saving 8-Pin

MSOP, making it ideal for applications requiring high

integration, small size and low power.
