TC54VN2002ECB713

TC54VN2002ECB713 is a member of the PMIC Supervisors family. It is a 5 V, low standby power supply monitor IC and is designed to reset a system in case of a low input power, brown-out or over-voltage condition. This IC is a must-have component in any system’s reset, power-on sequence, or other low-power applications. This article will discuss the application field and working principle of TC54VN2002ECB713.

TC54VN2002ECB713 is suitable for DC/DC converters that provide a regulated 5 V supply, such as those used in PC servers, telecommunications, and computer audio systems. It provides a stable voltage supply for a wide range of applications, ensuring a reliable system, and preventing damage due to power irregularities. With its high slew rate and quick-response suppression, this IC greatly reduces the risk of unwanted glitches and overshoots during power-supply start-up. This stability makes it an ideal choice for low-power applications and electronic systems in which stability requires minimizing dead time and minimizing current surge.

The working principle of the TC54VN2002ECB713 involves a reset signal generated in response to unfavorable power conditions. This signal is triggered when the input voltage drops below a preset threshold. The device also monitors for an over-voltage condition characterized by an output voltage exceeding its allowed range. This reset signal is then used to reset the system and the voltage regulator output going low. The system needs to reach a predetermined voltage level to start the reset sequence again.

In addition, the TC54VN2002ECB713 provides over-voltage protection by comparing the output voltage of the power supply to a preset threshold. If the output voltage exceeds the preset threshold, the IC sends a reset signal, causing the power supply output voltage to go low. This reset signal also ensures that when the power supply input voltage changes, the output voltage remains at or below the preset threshold. Moreover, when an abnormal voltage is detected on the output voltage, an internal voltage monitor circuit will shut down power to the main power supply source in order to avoid damage to the system.

Another important feature of the TC54VN2002ECB713 is its brown-out protection, which helps to avoid system shutdown due to prolonged low-input voltage situations. This IC supports a wide input voltage range to ensure reliable operation even in cases of sudden power loss. In addition, it provides a delayed reset signal when the input voltage recovers to provide recognition time for the system to detect the low voltage situation.

The reset signal from this IC is designed to be implemented in any system with a variety of reset methods such as momentary closure of reset inputs, latching reset inputs, and external reset circuits. This design gives system designers the flexibility to choose the reset scheme that works best for their application. Additionally, this IC comes with a low power consumption profile, making it an ideal choice in terms of sustainability.

In summary, the TC54VN2002ECB713 is a practical and reliable solution for low-power applications and systems. It is a must-have component in any system\'s reset, power-on sequence, or other low-power applications. With its wide slew rate and quick-response suppression, this IC offers superior protection against unstable input voltages, over-voltages, and overshoots. With its low power consumption, it is an ideal choice for designers seeking sustainable solutions.
