MAX17043: Battery Monitoring Done Right (Arduino & ESP32)
Note: Normally, you only have to connect the battery to the fuel gauge, and the fuel gauge to your microcontroller. The fuel gauge will pass along power to the microcontroller. However, in this case, my ESP32 board can''t be powered through its pins. It only accepts power over USB or the battery connector.
A microcontroller does not have an in-built battery, therefore you will need to provide an external battery source to make it work properly. Without providing a battery source, the microcontroller will be rendered useless.
One explanation could be the following:. Using an Atmega 328-PU with a 16MHz crystal on a 3 volt supply is out of spec. If you take a look at figure 29-1 the ATmega 328p datasheet on page 303 you''ll see the maximum frequency for the MCU for a given Vcc.. Also keep in mind that the voltage of the batteries drops of quickly after losing some …
Let''s imagine that we are powering solely the above circuit with a fully charged battery (i.e. no microcontroller or other components). In that case, the total amount of time that the LED would stay lit before the battery ran out of charge can be calculated by dividing the battery capacity by the power required by the LED and resistor.

Because the systems that drive the market for discrete logic are mostly not battery powered, and 2. ... it is no problem supplying a regulated operating voltage to power any microcontroller based system. Many applications need a well-regulated and noise-free power supply, and running directly from a battery would be problematic.
The battery must be new! Would a capacitor help ? i=C dv/dt, so C=i dt/dv. For the input voltage to drop from 6V to 3.5V (dv=2.5V) during dt=0.25s with i=55mA, this gives C=5500µF, to place in parallel with the battery, before the power switch. Not entirely practical, and not very "thin and fashionable" either, but doable.

A battery-operated microcontroller might consume 50 milliwatts. A microcontroller has a dedicated input device and often (but not always) has a small LED or LCD display for output. A microcontroller also takes input from the device it is controlling and controls the device by sending signals to different components in the device.

How to Greatly Improve Battery Power Efficiency for IoT Devices
In a typical IoT system, as shown in Figure 1, the wireless sensor node is mostly battery operated and, thus, inherently constrained by battery life. To maximize the life of the sensor node, power management is crucial. The duty cycle concept is a common practice for saving power in a sensor node. ... Microcontroller; Radio operation;
A voltage follower buffer amplifier circuit can overcome that, or you could use a power monitor IC, but that will add complexity and might end up adding power consumption. If you use microcontroller ADC remember to select the reference voltage to be something that doesn''t change when the battery voltage drops.
