TC54

Voltage Detector

Features

General Description

• Precise Detection Thresholds: Standard ±2.0%,

Custom ±1.0%

The TC54 Series are CMOS voltage detectors, suited

especially for battery-powered applications because of

their extremely low 1µA operating current and small

surface-mount packaging. Each part is laser trimmed to

the desired threshold voltage which can be specified

from 1.1V to 6.0V and 7.7V, for a 2% and 1.5V to 6.0V

for a 1% tolerance.

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

5-Pin SOT-23A (7.7V only)

• Low Current Drain: Typ. 1µA

• Wide Detection Range: 1.1V to 6.0V and 7.7V

• Wide Operating Voltage Range: 0.7V to 10V

The device includes a comparator, low-current high-

precision reference, laser-trimmed divider, hysteresis

circuit and output driver. The TC54 is available with

either an open-drain or complementary output stage.

Applications

• Battery Voltage Monitoring

• Microprocessor Reset

In operation, the TC54's output (V_OUT) remains in the

logic HIGH state as long as V_INis greater than the

specified threshold voltage (V_DET-). When V_INfalls

below V_DET- the output is driven to a logic LOW. V_OUT

remains LOW until V_INrises above V_DET- by an

amount V_HYST, whereupon it resets to a logic HIGH.

• System Brown-out Protection

• Switching Circuit in Battery Backup

• Level Discriminator
