PMIC (Power Management Integrated Circuit) is used to manage power distribution and disposal in power sensitive systems. This integrated circuit is made up of drivers, controllers and switches, allowing it to control and distribute power to many components of the system. Among all kinds of PMIC, Battery Management share a big portion of the domain. In particular, the Maxell\'s DS2780G+T&R can substantially improve the performance and service life of the system.

The DS2780G+T&R is a 6-bit programmable feature digital battery management system with two TTL inputs, two GPIOs and two switches. This digital battery system provides voltage, current and temperature monitoring to detect problems and take corrective measures like opening or closing on/off switches and adjustable short-circuit current protection. It can be used in industrial battery packs, USB power ports and other applications.

As far as the application field, the DS2780G+T&R is widely used in backup systems such as bank branches, communication base stations, surveillance systems and medical equipments. Besides, it’s also ideal for high power driven applications for automobile and machine tools.

In terms of working principle, the monitor engine of DS2780G+T&R supports a wide range of power measurements and regulation. The monitor engine is based on a specially designed high-speed voltage-to-frequency converter, from which it can accurately detect and measure voltage and current in various conditions. Aside from the monitor engine, the system also integrates temperature measurement with a high-precision temperature sense circuit, allowing it to accurately measure die temperature and the temperature of the environment.

Furthermore, the monitor engine of DS2780G+T&R also offers controlling capacity. It has 3 sets of dedicated comparators that monitor current, battery voltage and temperature, making it able to measure and justify thresholds even under higher battery voltage. Also, the system can detect abnormal states of the battery, such as over voltage, over current, under voltage and high temperature, which can be used to trigger some protection mode.

The DS2780G+T&R is equipped with two open-drain switches and two general-purpose outputpins. The two main switches are configured to open-source or open-drain, allowing users to set their required control actions according to their different needs in the system. The two GPIOs can be paired with the Error Interrupt and Temperature Interrupt registers and be used to indicate the overcurrent, overvoltage and overtemperature events of the system.

In a nutshell, DS2780G+T&R is an excellent choice for motion control, power management and battery applications since it can monitor, regulate and protects the system in a flexible and accurate manner. With its ultra-fast response time, reliable operation and robust design, the DS2780G+T&R can performance in harsh environment while saving cost and space.
