BQ20Z60DBT-R1

Power management ICs (PMICs) are integrated circuits used in portable devices to optimize battery life and power consumption. Battery management ICs are used to monitor, regulate and manage the input, output and charging operations of batteries used in portable electronic devices. BQ20Z60DBT-R1 is a rechargeable battery protection and monitoring integrated circuit (IC) designed for use in portable electronic applications including smart phones, tablets and other hand held devices.

The BQ20Z60DBT-R1 IC integrates four independent protection functions to ensure safe and controlled operation of Li-ion and Li-polymer batteries: under voltage protection, over voltage protection, charging over current protection and discharging over current protection.

Its main application field includes battery-powered tools, measurement equipment, security and medical systems, GPS, automotive electronics, etc. In these applications, BQ20Z60DBT-R1 ICs are used to help protect the battery from the damaging effects of over discharging, over charging, over current, over voltage, and overheating.

The working principle of BQ20Z60DBT-R1 is based on its internal high-accuracy voltage and current measurement circuitry. It measures the battery voltage, current, remaining capacity (SOC), and temperature in real time. When the battery is being charged, it compares the real-time data with stored parameters such as the target voltage and charge current to ensure that the battery is charged safely and accurately according to the predetermined parameters.

It also monitors internally the temperature of the battery, the selected charge algorithm and provides protection against over temperature, over voltage, and over current. When the battery is discharged, BQ20Z60DBT-R1 sets an appropriate minimum level to which the battery voltage should not be allowed to fall. In case it is exceeded, the IC immediately sets the battery voltage to a safe level and turns off the discharge pathway.

BQ20Z60DBT-R1 ICs offer high accuracy and stability, allowing for the safe and accurate charging and discharging of batteries. In addition, its integrated SMBus/I2C interface allows for data communication making it highly flexible and suitable for a wide range of applications.

In summary, BQ20Z60DBT-R1 IC is an advanced battery protection and monitoring IC designed for use in portable electronic products. Its main application areas include battery-powered tools, measurement equipment, security and medical systems, GPS, and automotive electronics. Its working principle is based on high accuracy voltage and current measurement circuitry and it monitors internally the temperature of the battery, the selected charge algorithm, and provides protection against over temperature, over voltage and over current.
