Power Management Integrated Circuit (PMIC) is an integrated circuit which combines functions of a variety of power management and control functions into a single package. There are a wide range of applications for PMICs, but one of the most important is the category of supervisors. Supervisors are special type of integrated circuits which are used for monitoring and management of multiple power sources.

BD5251FVE-TR is an example of this type of supervisor. It is a system-on-chip (SoC) IC which features multiple power management and control functions. It is intended for use in battery-powered portable consumer electronics devices. It is capable of controlling and monitoring multiple battery cells, as well as providing system level power management and control.

BD5251FVE-TR main application field is to provide power management and control for battery-powered devices. It provides functions for monitoring the health and voltage of multiple batteries and for controlling the charge and discharge of the batteries. It also provides system power management and control functions, such as power timing and system reset. Furthermore, it provides over-temperature protection, over current protection and short circuit protection features.

The working principle of BD5251FVE-TR is based on a state machine. The state machine consists of a number of states which correspond to various phases of the power management process. For example, when the battery voltage is low, the governor will enter the “discharge” state. This initiates the battery cell discharge process with the controlling parameters set in the configuration registers. As the battery voltage rises again, the governor will enter the “charge” state, initiating the battery cell charging process.

When the battery voltage reaches the low or high limits, the governor will enter the “stop” state, stopping the power management process. Other states may also be used for system level control and protection, such as the “reset” state for system reset, or the “over-temperature” state for over-temperature protection. This state machine allows for flexible and efficient power management and control of multiple power sources.

In conclusion, the BD5251FVE-TR is an example of a Supervisor IC for power management and control applications. Its main application field is for battery-powered portable consumer electronics devices, and its working principle is based on a state machine with multiple states for power management and control. It provides features such as over-temperature protection, over-current protection and short circuit protection, as well as system level power management and control functions.
