TC54

Voltage Detector

Features

General Description

• ±2.0% Detection Thresholds

The TC54 series are CMOS voltage detectors that are

especially well suited for battery-powered applications

because of their extremely low 1 µA operating current

and small surface-mount packaging. Each part is laser-

trimmed to the desired threshold voltage, which can be

specified from 1.4V to 6.0V with a 2% tolerance.

• Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89,

and TO-92

• Low Current Drain: 1 µA (Typical)

• Wide Detection Range: 1.1V to 6.0V

• Wide Operating Voltage Range: 0.7V to 10V

The TC54 is available with either an open-drain or com-

plementary output stage. During operation, the TC54's

output (V_OUT) remains in the logic-high state as long as

V_INis greater than the specified threshold voltage

Applications

• Battery Voltage Monitoring

• Microprocessor Reset

–

(V_DET). When V_INfalls below V_DET, the output is

driven to a logic-low. V_OUTremains low until V_INrises

• System Brown-Out Protection

• Switching Circuit in Battery Backup

• Level Discriminator

–

above V_DETby an amount V_HYST, whereupon it

resets to a logic-high.
