Device Overview

Summary

The TC1272A are cost-effective system supervisor circuits designed to monitor VDD in digital systems and provide a reset signal to the host processor, when necessary. No external components are required. The reset output is driven active within 65 µsec (typ.) of VDD falling through the reset voltage threshold. RESET is maintained active for a minimum of 140 msec after VDD rises above the reset threshold. The TC1272A has a complimentary output. The output of the TC1272A is valid down to VDD = 1.2V. The device is available in a 3-Pin SOT-23B package.

Voltage Supervisor Evaluation Board ( VSUPEV )

The Voltage Supervisor SOT23 Evaluation Board allows the system designer to quickly evaluate the operation of Microchip’s Voltage Supervisors and Voltage Detectors in the SOT-23-3 package. The board has been made generic so that other SOT-23-3 devices (such as LDOs and Voltage References) may also be evaluated using this board. This kit comes with four blank PCBs to allow the designer to...
