Overview of the BQ24770RUYT Battery Management PMIC

The BQ24770RUYT battery management PMIC is a high-power device, intended for use with Lithium-Ion battery packs up to 600V and 12A. It provides a complete solution for electrical power management and protection. The device provides integrated over-current protection, battery temperature monitoring, and voltage regulation. It also includes a integrated rechargeable battery charger, allowing for fast and safe charging of Lithium-Ion cells. Additionally, the device includes a wide range of safety features, such as over-voltage protection and thermal shutdown.

BQ24770RUYT Working Principle

The BQ24770RUYT PMIC uses an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) to measure and control the current and voltage. The ADC measures the battery voltage, current, and temperature. The DAC then outputs a precise voltage to regulate the power to the battery. The PMIC also includes a charging controller, which manages the charging process, and a host controller, which communicates with the external system.

The charging controller adjusts the battery charge current based on the current, voltage, and temperature measurements. It also determines the charging parameters, such as the end-of-charge voltage, charge current, and charge time. The host controller checks the status of the battery and the power system, and communicates these parameters to the charging controller. In addition, the host controller manages the current, voltage, and temperature monitoring.
