TC54 Series

VOLTAGE DETECTOR

FEATURES

GENERAL DESCRIPTION

ꢀ Precise Detection Thresholds .... Standard ± 2.0%

Custom ± 1.0%

ꢀ Small Packages ......3-Pin SOT-23A, 3-Pin SOT-89,

3-Pin TO-92

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

ꢀ Wide Detection Range..........................1.1V to 6.0V

ꢀ Wide Operating Voltage Range ............ 0.7V to 10V

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,

in 0.1V steps for a 2% and 1.5V to 6.0V for a 1% tolerance.

The device includes a comparator, low-current high-

precisionreference,laser-trimmeddivider,hysteresiscircuit

andoutputdriver. TheTC54isavailablewitheitheranopen-

drain or complementary output stage.

APPLICATIONS

ꢀ Battery Voltage Monitoring

ꢀ Microprocessor Reset

ꢀ System Brownout Protection

ꢀ Switching Circuit in Battery Backup

ꢀ Level Discriminator

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_D^–_ET). When V_INfalls below

V_D^–_ET, the output is driven to a logic LOW. V_OUTremains

LOW until V_INrises above V_D^–_ETby an amount V_HYST

whereupon it resets to a logic HIGH.
