Product Benefits

- thermal management and overvoltage protection
Thermal management is another major challenge for battery charger designers. Every charger chip experiences a voltage drop during the charging process due to heat dissipation. To avoid battery damage or system shutdown, most chargers incorporate some form of control mechanism to manage heat build-up. Newer devices use more sophisticated feedback techniques to continuously monitor die temperature and adjust the charge current dynamically or by calculation at a rate proportional to the change in ambient temperature. This built-in intelligence allows the current charger chip to gradually reduce the charging current until thermal equilibrium is reached and the die temperature stops rising. This technology allows the charger to continuously charge the battery at the maximum possible current without causing the system to shut down, thus reducing battery charging time. Most newer devices today will also typically add an overvoltage protection mechanism.
The charger BQ25616JRTWRprovides various safety features for battery charging and system operations, including battery negative temperature coefficient thermistor monitoring, charging safety timer and overvoltage and over-current protections. Thermal regulation reduces charge current when the junction temperature exceeds 110°C. The STAT output reports the charging status and any fault conditions.

Application Scenarios

The battery charger chip belongs to a kind of power management chip, the application range is very wide. The development of power management chips is important for improving the performance of the whole machine, the choice of power management chips is directly related to the needs of the system, while the development of digital power management chips still needs to cross the cost barrier.
