MAX17525ATP+T

The concept of power management is essential to the modern world.Maxim Integrated’s MAX17525ATP+T is a specialized power management integrated circuit (PMIC) which combines a buck-boost dc-to-dc converter, an energy harvesting boost DC/DC converter, a low dropout regulator (LDO), and several protection features including over-voltage protection (OVP) and reverse-current protection (RCP) in a single device. This innovative design offers superior efficiency, high power density and a wide operating temperature range to allow for performance in a variety of applications.

The application fields for MAX17525ATP+T include power management for various battery-based energy harvesting products and applications. This can range from personal healthcare products such as wearables, to remote monitoring systems and industrial/agricultural embedded systems. This device is a good choice for these applications due to its wide input voltage ranges, wide temperature operation and its low quiescent current. It also provides extensive protection features, including over-voltage protection (OVP) and reverse-current protection (RCP), reducing the need for additional components.

The working principle of MAX17525ATP+T is as follows. The input voltage is first monitored by the OVP, which monitors the input voltage and prevents it from exceeding a user-defined threshold. If the voltage is exceeded, the OVP will trigger and the power supply will be disconnected and the system will enter an inactive state. When the voltage drops below the OVP threshold, the power supply will reconnect, allowing the system to resume normal operation.

The energy supplied from the input is then transferred through the buck-boost converter, where it is regulated to the specified output voltage level. This output voltage is then regulated further by the LDO, which reduces fluctuations in voltage and ensures a consistent, stable output. The RCP ensures that the system does not output more power than it receives from the input. This works by monitoring the current and disconnecting the power supply if it exceeds the user-defined threshold.

The MAX17525ATP+T is a specialized PMIC that offers a wide range of features and protection, making it suitable for a variety of applications. Its wide input voltage range and wide temperature range allow it to be used in extreme conditions, while its low quiescent current ensures efficient power consumption. Lastly, its extensive protection features, such as OVP and RCP, make it an ideal choice for power management in different applications.
