Description:Microchip TC54 Voltage Detector


The TC54 series are CMOS voltage detectors that are especially well suited for battery-powered applications
because of their extremely low 1 uA operating current and small surface-mount packaging. Each part is lasertrimmed
to the desired threshold voltage, which can be specified from 1.4V to 7.7V for a 2% tolerance and from
1.5V to 6.0V for a 1% tolerance.
The device includes a comparator, low-current highprecision reference, laser-trimmed divider, hysteresis
circuit and output driver. The TC54 is available with either an open-drain or complementary output stage.
During operation, the TC54's 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, whereupon it resets to a logic-high.

Features: Precise Detection Thresholds: Standard ±2.0%, Custom ±1.0% Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89, TO-92 and 5-Pin SOT-23A (7.7V only) Low Current Drain: Typ. 1 uA Wide Detection Range: 1.1V to 6.0V and 7.7V Wide Operating Voltage Range: 0.7V to 10V Applications: Battery Voltage Monitoring Microprocessor Reset System Brown-Out Protection Switching Circuit in Battery Backup Level Discriminator
