TC54
Voltage Detector
Features: General Description: В±2.0% Detection Thresholds Small Packages: 3-Pin SOT-23A, SOT-89, and
TO-92 Low Current Drain: 1 ВµA, typical Wide Detection Range: 1.1V to 6.0V Wide Operating Voltage Range: 0.7V to 10V The TC54 series are CMOS voltage detectors especially well-suited for battery-powered applications
because of their extremely low 1 ВµA operating current
and small surface-mount packaging. Each part is lasertrimmed to the desired threshold voltage, which can be
specified from 1.4V to 6.0V with a 2% tolerance.
The TC54 is available with either an open-drain or complementary output stage. During operation, the output
(VOUT) remains in the logic-high state as long as VIN is
greater than the specified threshold voltage (VDET –).
When VIN falls below VDET –, the output is driven to a
logic-low. VOUT remains low until VIN rises above
VDET – by an amount VHYST, when it resets to a logichigh state. Applications: Battery Voltage Monitoring
