Design of battery charger with power path controller and fuel gauge for point of sale (POS) terminal

摘要

A POS system or Point of sale (POS) terminal is a combination of hardware and software. POS terminal is a replacement for cash register, it has ability to record and track customer orders and it is used to process credit, debit card payments and many other functions. POS system requires suitable input power for its operation. Battery charger with power path controller (BQ24171) helps to charge the battery efficiently and also select the appropriate power path to the system load. Fuel gauge (34Z100) IC has inbuilt coulomb counter, Which helps to measure the charge added to and removed from the battery. MAGIK II [Media Accelerated Graphics Innovation Kit], which is a low power compact module for multimedia applications and i.MX6 processor is embedded on it. i.MX6 processors are automotive and infotainment processors represent Freescale Semiconductor's latest achievement in integrated multimedia applications processors.
