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 additional 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.
Charging Gate Driver Circuit
The Charging Gate drive Circuit is composed of the Gate driver, MOSFET Half Bridge, and Power Inductor with Filter. The Gate driver is directly controlled by the ICC MCU, typically through a precision PWM. 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.
Voltage and Current sensing
In order for Iontra Charging to be implemented, the ICC MCU needs feedback on battery voltage, current, temperate, and state of charge. If the Op-Amps shown are currently designed in your application, some adjustments may be needed for operability with the ICC. If not present, these elements will need to be added for the ICC direct sensing.
Bi-directional Switch
The Bi-directional switch or equivalent circuit should be implemented to ensure the battery can power the system when not charging.
