Maxim Integrated’s MAX17502 integrated circuit offers a high performance battery backed supercapacitor charger and balancer controller with a DC-to-DC converter and a buck regulator, which fits any appications where a reliable battery backup algorithm is required to maintain voltage and current accuracy.

MAX17502BATB+T Application Field

MAX17502BATB+T from Maxim Integrated is designed for a range of applications, such as energy storage systems, data centers, automotive, telecommunication and industrial battery backup systems, that need to regulate and balance the total system voltage and current. The device can also provide a secondary super-capacitor input with an integrated battery-backed charger, so it can be used in applications where the main battery voltage is less than the supercap charging voltage. In addition, it features current monitoring and also includes alarms to detect battery backup failure, secondary input connection failure and any extra faults.

The MAX17502BATB+T integrated circuit from Maxim Integrated is designed for high efficiency and to provide a robust, reliable and safe power supply for any system using it. Its host IC powers up the IC, monitors battery voltage to ensure safety, performs a charging and boosting algorithm and provides a low-power standby mode. It also maintains systems with a high amount of power loads, while its integrated buck switching converter provides greater power efficiency and good load transient response.

MAX17502BATB+T Working Principle

The MAX17502BATB+T integrated circuit from Maxim Integrated includes a multi-channel charger and balancer controller (MCCC), which eliminates a large number of external components. This takes away the task of handling the power management of the battery, as well as the cascading of multiple channels. As a result, it simplifies overall system design and provides reliable system protection for instances of over-temperature, over-voltage, under-voltage and battery over-discharge.

The MCCC from Maxim Integrated works by allowing the user to configure and program the system according to their needs. It also regulates, and maintains, the balance between the system’s batteries, either by auto discharging or by performing a balancing process. The device is also equipped with a voltage monitor, which is used to alert the user when the voltage of a single cell has exceeded the settable limit. Additionally, the MCCC integrates a pre-charge circuit which can be used to balance the micro-circuit in case of a surge or a short circuit in the load application.

The MAX17502BATB+T also includes a buck regulator, which is used to maintain system voltage during battery backup operations. This controller comprises of a voltage-mode PWM, which ensures stability and also increases current efficiency. It also features a switching control circuitry, which makes sure that the system is not adversely affected by low-level noise. Finally, the device features an integrated ripple filtering network which helps reduce the system’s total output noise.

The MAX17502BATB+T from Maxim Integrated is an integrated circuit that has been designed to offer great performance and efficiency in battery backup solutions. It combines all the necessary battery protection and balancing, as well as a buck regulator, and it requires fewer components for a simpler system design. All this makes it ideal for applications that require reliable, robust and safe backup options.
