PMIC (Power Management Integrated Circuits) is widely used to regulate power supply and monitor system voltage. Supervisors are the most important subcategory of PMICs, as they monitor various operating conditions of systems and act accordingly. TLV809L30DBZT is an advanced supervisor chip that widely used in many different applications. This document provides a detailed overview of TLV809L30DBZT features, its application field, and its underlying working principle.

Features of TLV809L30DBZT

TLV809L30DBZT is a single chip, ultra low-power supervisor that monitors six different voltages. It features an operating range of 2.4 V to 6 V and a maximum supply current of only 500 nA. It is designed to operate in a very low-power environment and is highly accurate, with a voltage accuracy range of ±3%. It has two detected voltages, one being an under-voltage detection that triggers a user-configurable reset and the second being an over-voltage detection. It also includes an adjustable timeout on the reset output, allowing it to reset the system after a certain period of time. Furthermore, TLV809L30DBZT includes an open-drain push-pull output, which can either be used as a voltage monitoring pin or as a reset output. Last but not least, the device also includes an internal temperature and voltage reference, enabling temperature compensation.

Application Field

TLV809L30DBZT is designed to provide a secure power supply to a wide range of applications, including embedded systems, IoT devices, and consumer electronics products. Its features, including ultra-low power consumption, adjustable timeout, voltage accuracy and temperature compensation make it a perfect fit for many portable devices and systems that require a secure power supply. In addition, TLV809L30DBZT can also be used in medical equipment, where it can be used to monitor and maintain the system’s power supply.

Working Principle

TLV809L30DBZT works by monitoring the system’s voltage and temperature. When the voltage drops below a certain threshold, the device triggers a reset output, or voltage monitoring pin, which can be used to reset the system to its original levels. The device also contains an adjustable time-out circuit, which can be used to reset the system after a certain period of time, in case the voltage does not return to its original levels. The device is also capable of compensating for changes in temperature, as it contains an internal temperature and voltage reference. This ensures that the device’s measurements are accurate, regardless of the operating temperature.

Conclusion

TLV809L30DBZT is a powerful supervisor chip that is used in a wide range of applications, from embedded systems to medical equipment. Its features, including ultra-low power consumption, adjustable timeout, voltage accuracy and temperature compensation make it suitable for a variety of environments. It works by monitoring the system’s voltage and temperature, and is capable of resetting the system in case the voltage drops below a certain threshold. Ultimately, TLV809L30DBZT can be used to provide a secure power supply to a wide range of applications.
