GENERAL DESCRIPTION

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 2.1V to 6.0V, in 0.1V steps.

FEATURES

■ Precise Detection Thresholds .... Standard ± 2.0 Custom ± 1.0

■ Small Packages ........... SOT-23A-3, SOT-89, TO-92

■ Low Current Drain ..................................... Typ. 1μA

■ Wide Detection Range .......................... 2.1V to 6.0V

■ Wide Operating Voltage Range ............ 1.5V to 10V

APPLICATIONS

■ Battery Voltage Monitoring

■ Microprocessor Reset

■ System Brownout Protection

■ Switching Circuit in Battery Backup

■ Level Discriminator
