Microcontrollers cannot function without a power supply. They have no built-in battery, meaning they are powered with external sources. The goal is to have an energy source that outputs the microcontroller’s required current and voltage.
The goal is to have an energy source that outputs the microcontroller’s required current and voltage. While microcontrollers can often be powered by a direct or alternating current, for added security, many developers use external batteries to support necessary functions.

The MSP430 microcontrollers are a good fit for a Li-ion battery charger solution, because of integrated peripherals like the high-resolution ADC and watchdog timer.
Additionally, batteries enable devices to go cordless. A device that doesn’t need to be plugged into a wall can be more easily transported. When using current microcontroller battery technology, there are certain limitations because a battery can only provide so much power for so long.
Corresponding technological advances must be able to sustain these new devices. This is one reason why City Labs has developed long-lasting NanoTritium™ batteries to power low-energy microelectronics. Microcontrollers cannot function without a power supply. They have no built-in battery, meaning they are powered with external sources.
