This PMIC supports various types of batteries along with other external power sources, such as wall adapters and USB, eliminating the need for multiple power management ICs (PMICs).

An attractive feature of the TPS65920A2ZCHR’s battery-powered devices is its compatibility with conventional chemistries, such as Li-ion and Li-polymer, as well as the new Extended Life Batteries (ELBs). This means that the TPS65920A2ZCHR is ideal for applications ranging from high-performance products to those with extended battery life.

The TPS65920A2ZCHR supports up to 4.6V input and offers excellent transient response. It has comprehensive power management capabilities, including battery charging, voltage sequencing and sequencing between multiple power sources. The device supports a wide range of voltage levels, up to 6A power input, and provides up to 95% efficiency.

Moreover, the TPS65920A2ZCHR is one of the most advanced power management solutions on the market due to its integration of protection features. It contains numerous safety features for protection against overvoltage, overcurrent, undervoltage, undercurrent, short circuit, thermal overload, and reverse polarity. All these protection techniques come together to provide a reliable and robust solution for today\'s battery-powered systems.

Working Principle

The TPS65920A2ZCHR works under the principle of detecting input power and automatically adjusting the output voltage and current required by the application. Its main components include a voltage sequencer, power management modules, power switches and a multiplexer.

The controller operates in the following manner. First, it identifies the available power sources and determines the most suitable one. Once the power source has been determined, the voltage and current levels are regulated according to the application requirements, and then the power outputs are optimized. The controller also protects the system against input, output, and battery faults.

The multiplexer allows a flexible combination of power sources in order to maximize system performance and reduce cost. The multiplexer is also capable of automatically switching between different power sources, such as battery and wall adapter, to ensure that the required output is maintained even when the battery level is low.

The TPS65920A2ZCHR is also able to control low-power modes for the application, such as sleep mode, by automatically switching between power sources. This ensures that the application draws minimal power when it is not in use.

In addition, the device can also monitor the system, providing information on battery health and level of charge. The TPS65920A2ZCHR can also provide diagnostic information in order to identify faults and take corrective action.

Finally, the TPS65920A2ZCHR can also be used for battery charging. It supports both standard and fast-charge mode, as well as safety features to prevent overcharging or damage to the battery.

Conclusion

The TPS65920A2ZCHR is an advanced power management integrated circuit that is suitable for a variety of battery-powered applications. Its comprehensive power management capabilities provide the flexibility and ease of use to customers when designing their systems. The device offers exceptional input, output, and battery protection,along with comprehensive monitoring and diagnostic capabilities. In addition, the TPS65920A2ZCHR also supports battery charging and low-power modes.
