Power management integrated circuits (PMICs) are a family of microprocessors specifically designed to manage the flow of power used in electronics. PMICs are used across a variety of electronic applications, including mobile devices, wearables, healthcare devices, and Industrial Internet of Things (IIoT) applications. The BQ26100DRPR is a PMIC specifically designed to manage the energy flow in a rechargeable battery. This article will discuss the BQ26100DRPR, its application field and working principle.

Overview

The BQ26100DRPR is a battery management integrated circuit (BMIC), designed to monitor, manage and protect the energy stored in a rechargeable lithium-ion battery. It is part of the MPS BQ26100 Family of PMICs, an advanced solution for battery monitoring and management for high-end applications. With a very low quiescent current of 40µA, the BQ26100DRPR offers efficient current and voltage management to extend the battery life. It also provides multi-cell balancing to ensure a long operating life. The BQ26100DRPR operates with a voltage range of 2.7V to 4.4V.

Features

The BQ26100DRPR is designed to maintain a high level of safety and reliability in battery management applications. It offers an array of features to maximize safety, such as an over-voltage protection (OVP) and an over-temperature protection (OTP) feature. It also features an auto-restart protection and a programmable Cell-OD (cell over-discharge) protection. The BQ26100DRPR also features under-voltage protection (UVP) and zero-drain protection, which prevents the cell from discharging beyond zero volts. In addition, the BQ26100DRPR provides an overcharge protection (OCP), short-circuit protection (SCP), and thermal runaway protection (TRP).

The BQ26100DRPR also enables efficient and precise battery monitoring, thanks to its integrated analog-to-digital convert (ADC). With its advanced precision, the BQ26100DRPR provides an accurate reading of the battery’s voltage and current. With its integrated buck-boost converter, the BQ26100DRPR can adjust the direction of the current flow to either charge or discharge the battery. The BQ26100DRPR also offers an interesting feature known as Adaptive Cell Balancing (ACB), which eliminates the need to manually balance the cells.

Applications

The BQ26100DRPR is designed to meet the demands of high-end applications. It is optimized for use in a variety of applications, including portable devices, wearables, healthcare, and IIoT. Its 32-bit architecture enables efficient and precise monitoring and management of the battery. Its small form factor and low power consumption also make it ideal for use in applications where energy efficiency is paramount. The BQ26100DRPR can also be used in applications where batch/lot charging and discharging is required, such as in computers, gaming consoles and tablets.

Working Principle

The BQ26100DRPR is a battery management and protection IC. It works by monitoring the voltage and current of the battery, and then adjusting the charge/discharge current direction and flow as needed. The BQ26100DRPR also provides protection to the system with its OVP, SCP, UVP, OCP, and TRP features. In addition, it is equipped with Adaptive Cell Balancing (ACB), which automatically balances cells in a multi-cell battery pack to ensure the battery’s long working life.

Furthermore, the BQ26100DRPR integrates an analog-to-digital converter (ADC) to monitor the battery’s voltage and current. With its precision and accuracy, the BQ26100DRPR can trickle charge or discharge the battery to maintain optimal levels and maximize battery life. With its low power consumption and wide voltage range, the BQ26100DRPR is an ideal solution for battery pack management and protection in high-end applications, such as IIoT, wearables and healthcare.
