TC1037/TC1038/TC1039

Linear Building Block – Single Comparator in SOT Packages

Features

General Description

• Tiny SOT-23A Packages

The TC1037/TC1038/TC1039 are single, low-power

comparators designed for low-power applications.

• Optimized for Single Supply Operation

• Ultra Low Input Bias Current: Less than 100pA

These comparators are specifically designed for

operation from a single supply. However, operation

from dual supplies also is possible, and power supply

current is independent of the magnitude of the power

supply voltage. The TC1037/TC1038/TC1039 operate

• Low Quiescent Current: 4µA (TC1037),

Shutdown Mode: 4µA, 0.05µA (TC1038),

6µA (TC1039)

• Shutdown Mode (TC1038)

from two 1.5V alkaline cells down to V = 1.8V. Active

• 2.0% Accurate Independent Voltage Reference

(TC1039)

supply current is 4µA for the TC1037/TC1038 and 6µA

for the TC1039. Input and output swing of these

devices is rail-to-rail.

• Rail-to-Rail Inputs and Outputs

• Operation Down to V = 1.8V

An active low shutdown input, SHDN, is available on

the TC1038 and disables the comparator, placing its

output in a high-impedance state. The TC1038 draws

only 0.05µA (typical) when the shutdown mode is

active.

Applications

• Power Management Circuits

• Battery Operated Equipment

• Consumer Products

An internally biased 1.20V bandgap reference is

included in the TC1039. The reference is accurate to

2.0 percent tolerance. This reference is independent of

the comparator in the TC1039.

Range

Packaged in a 5-Pin SOT-23A (TC1037) or 6-Pin

SOT-23A (TC1038/TC1039), these single comparators

are ideal for applications requiring high integration,

small size and low power.
