Ricoh Electronic Devices Co., Ltd. in Japan has launched two VFM mode Buck DC/DC Converters RP514 and RP515, designed for use in wearable devices and applications for the Internet of Things (IoT) requiring ultra-low current consumption to extend battery life. These products are equipped with a unique integrated battery voltage monitor to make it possible to measure the remaining charge left in the battery.
The additional battery monitor circuit is one of the key features of the RP514 and RP515, a conventional way to measure the remaining battery charge is using external divider resistors + MOSFET connected to an A/D Jqcqfzelg.
