.Power management integrated circuit (PMIC) is an important component for modern embedded products. It can efficiently manage power and reduce power consumption, which plays an important role in improving the battery life and system performance. In this article, we will introduce the BQ7790500PW device, which belongs to the PMIC - Battery Management, to see its application field and working principle.BQ7790500PW is a high-performance Li-Ion/Li-polymer battery pack system monitor and balance IC, which integrated a tiny MCU, a two-channel coulomb counter, voltage measurement and protection circuity. It operates as an embedded microcontroller and can run precision algorithms to monitor and balance Li-Ion/Li-polymer battery pack with up to 8 series cells.In terms of application fields, BQ7790500PW can provide the utmost flexibility for a variety of battery pack designs. It is widely used for many applications such as energy storage, medical equipment, commercial equipment, power tools, consumer products, vehicle electric power systems and so on. It is especially beneficial for applications that have capactive loads, like high-power class D amplifiers and high-end mobile phone audio systems.Now let’s take a look at the working principle of BQ7790500PW. It includes three main stages: monitoring, balancing and protection. It can accurately measure the battery pack voltage and current, calculate the remaining capacity and determine the state of the battery pack. It also provides the user with important health indications such as remaining capacity, health state, and temperature. Then the BQ7790500PW will control the balancing circuit by turning on/off the switch. In the protection stage, this device protects the battery pack by providing comprehensive overcurrent and overvoltage protections.In conclusion, BQ7790500PW device is a powerful and reliable single-chip battery management device. It is widely applied in various battery packs to accurately monitor and balance the Li-Ion/Li-polymer battery, as well as providing comprehensive overcurrent and overvoltage protections.
