Learn MoreFor many low-power battery-powered applications, standby power can be the primary impact to battery life, and it is critical that developers consider how the features required in the application impact the standby current. It can make a difference in years of battery life or save on system cost by using a lower capacity, less expensive battery.
Learn MoreAn integrated low drop out (LDO) regulator can help significantly reduce power consumption. For example, a battery-powered MCU without an LDO regulator can consume up to 50% more power from fully-charged batteries delivering about 3Vdc, compared with depleted batteries delivering about 1.8Vdc.
Learn MoreBattery based solutions come with the inevitable caveat of battery replacement, which translates to an incremental cost, throughout their ownership. ONiO.zero circumvents this pain point and slashes the cost of ownership. It can be used to power sensors and devices for years, without having to spare a thought about maintenance - …

Learn MoreBecause 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.
Learn MoreOne 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 …
