Introduction

The TC1277-5ENBTR is a Supervisory and Control device belonging to the Power Management IC (PMIC) Supervisors family. It is a high performance, low power and fully integrated device that is designed to monitor and control power system supply sequencing and sequencing delays.

Application Field

The TC1277-5ENBTR can be used in a wide range of applications, including: systems with multiple power supplies, power sequencing and sequencing delays, high voltage dropout monitor, supply over or under voltage protection, high voltage communications isolation, over temperature monitors and protection, and other uses in systems operating from a variety of power sources and with high input voltage.

The TC1277-5ENBTR is ideal for use in applications such as telecom, networking and industrial markets where precision control and monitoring of power sources is critical to the reliable operation of the system.

Working Principle

The TC1277-5ENBTR operates by sensing the power source voltage and comparing it to a programmable setpoint. The compare action is used to generate a supervisory reset signal. The reset signal is output as an active low signal. The reset signal is used to connect or disconnect the power supply, as well as to initiate the sequencing delay.

The sequencing of the TC1277-5ENBTR is controlled by a programmable timing circuit, which combines both an adjustable power-on reset and adjustable power-off reset function. When the device is powered up, the first stage of timing is used to ensure the system is properly powered up and ready for operation. When the device is powered down, this same stage of timing causes the system to be safely shut down in a controlled manner. This two-stage timing process ensures that all levels of the system are properly maintained and synchronised.

The TC1277-5ENBTR also incorporates an integrated Voltage Regulator that provides precise regulation and dynamic response for the power system. This regulator can be used to provide precise output current and voltage from any power source that is within a certain voltage range. It also has built-in current limiting and thermal protection, which help to ensure the accurate and safe operation of the system.

The TC1277-5ENBTR also integrates a wide range of other features such as undervoltage and overvoltage protection and monitor, temperature monitor and protection, status monitoring, system sequencing and sequencing delays, and more.

Conclusion

In conclusion, the TC1277-5ENBTR is a high performance and low power device that is designed to monitor and control power system supply sequencing and sequencing delays. It features a wide range of features such as voltage and temperature monitoring, current limit sensing, system sequencing and sequencing delays, and more. It is an ideal choice for applications such as telecom, networking and industrial markets where precise control and monitoring of power sources is critical to the reliable operation of the system.
