Power management integrated circuits (PMICs) are essential components in modern electronic systems, providing the necessary flexibility in power distribution and supply sequencing necessary to optimize power and performance. PMICs are usually segmented into four categories—power controllers, voltage references, voltage regulators, and supervisors—each of which may offer further subcategories with specific capabilities. Supervisors, in particular, monitor the operation of a system and determine if a fault condition has occurred. This can then be used to communicate system information to other components or take corrective action, offering an extra level of safety and reliability.

MAX6735KALTD3+T application field and working principle:

The MAX6735KALTD3+T is a high performance always-on supervisor for single-cell Li-ion and Li-polymer batteries. The device includes several highly popular features such as automated system enable and disable. It is also temperature-qualifiable and offers protection against reverse voltage on inputs and outputs, as well as an open battery-detection function, which maximizes system safety. The MAX6735KALTD3+T is designed for use in a wide range of applications, including automotive, industrial, handheld, and renewable energy.

The MAX6735KALTD3+T is based on the MAX6735 device, which is a subcategory of PMIC supervisor solutions designed for single-cell Li-ion and Li-polymer batteries. The MAX6735KALTD3+T features several built-in protection features, such as reverse-voltage protection, overvoltage protection, and power-on reset. The device also includes an open-battery detection function that informs the system in the event of an open battery connection. Furthermore, the MAX6735KALTD3+T includes an automated system enable and disable feature that helps to further optimize power management.

In terms of its operation, the MAX6735KALTD3+T monitor the voltage on either a single-cell Li-ion or Li-polymer battery to establish when it should enable or disable the operating system. The device has an operating temperature range of -40°C to 125°C, and can provide a reset signal to the processor/controller if the battery voltage drops below the set threshold. Additionally, the MAX6735KALTD3+T can provide an early warning alert (EWA) if the battery voltage drops below a lower threshold. This helps the system take corrective measures, such as draining the battery or initiating a clean shutdown, before the battery voltage reaches the reset threshold.

The MAX6735KALTD3+T is designed to be used with a single Li-ion or Li-polymer cell. It can be used as an integrated supervisor for a system as well as a primary backup supervisor in situations when energy from an alternative power source is needed. Furthermore, it can be used in applications where a high degree of system flexibility is required. In addition, it can be used for supervisors for system communication and monitoring, with an operating temperature range of -40°C to 125°C.

The MAX6735KALTD3+T is a highly reliable and efficient device with several key features that make it an ideal choice for single-cell Li-ion and Li-polymer battery monitoring and protection. With its integrated protections, reverse-voltage protection, overvoltage protection, and power-on reset, it makes a powerful and dependable addition to any power management system. Furthermore, its automated system enable/disable feature offers an extra level of safety and reliability.
