The TC54VN4502EMB713 is an integrated circuit belonging to the class of PMIC - Supervisors. This chip, developed and manufactured by Texas Instruments, is an advanced low-power CMOS supervisor with a built-in temperature compensation feature.

Application Field

The application field of the TC54VN4502EMB713 chip is mainly associated to the monitoring and resetting of electronic systems. This versatile supervisor can quickly detect any power failure and initiate a reset of the system as soon as possible. It is ideal for applications that require precise and reliable reset control such as telecommunications, networking, medical and industrial automation.

The TC54VN4502EMB713 also helps to prevent microprocessor systems from runaway code, and protect against erratic power-up/ground bounce. The device also offers a Push-Button Reset which can be used prevent system lock-ups during software development and troubleshooting.

Due to its high accuracy, low current consumption and robust thermal sensing, the TC54VN4502EMB713 supervisor is able to reliably detect intermittent or unexpected system operating conditions.

Working Principle

The TC54VN4502EMB713 utilises an advanced CMOS technology that enables the device to operate with high accuracy without needing any external components. The device also provides two independent voltage inputs (1.8V and 3.3V references). The voltage references are an essential component of the monitoring functionality, as they can detect a fault when the output voltage falls outside the set threshold.

The device also contains a temperature compensation component that helps to protect against false triggering when the temperature of the surrounding environment shifts. When the temperature shifts, the resistance of the temperature-sensing component also shifts and can lead to a false fault detection. With the temperature compensation component, this false triggering is prevented and reliable detection is always maintained.

The device also includes a push-button reset circuit which is activated when a user-defined voltage level is applied. This allows the user to manually reset the system in the case of a system failure.

The TC54VN4502EMB713 is suitable for applications where a reliable reset monitoring and control is needed. Its small package size and low-power operation makes it ideal for embedded systems with limited space or power budget.
