Major Components:
Iontra Charge Control MCU (ICC)
The ICC MCU is required to run the Iontra charging algorithm, controls the charging circuit, stores battery specific recipe information, and gathers feedback on battery vitals. Depending on your requirements or the MCU chosen, the ICC MCU can also accommodate your application’s functionality. The ICC MCU has certain requirements in order to be capable of Iontra charging. Iontra’s Iontic MCU covers these needs and allows your functionality in an independent core, while lowering solution cost. For a list of third party MCUs that are Iontra capable, please contact Iontra directly.
High Power Stage
The High Power Stage of the USB-C input is directly controlled by the ICC MCU, typically through a precision PWM. Typically this circuit is composed of a gate driver and a discrete buck design. Iontra can work directly with you for the architecture and design of this circuit to meet both your end equipment’s and Iontra charging needs.
Feedback Circuit
In order for Iontra Charging to be implemented, the ICC MCU needs feedback on battery voltage, current, temperate, and state of charge. Depending on your current implementation, this can be accomplished with updates from your BMS chip. In most cases, direct feedback is needed to the ICC MCU to accomplish Iontra charging.
Battery Monitor and Battery Protection
Monitoring and protection ICs for the battery may need to be adjusted to accommodate Iontra charging techniques. This may include enabling unused features or adjusting charge limits.
