AN84910UA
High accuracy voltage detection Battery Voltage Measurement IC AN84910UA Overview AN84910UA is an IC used to measure battery voltages. This IC can measure a maximum of 53V of common input voltage of 10 batteries connected in series and therefore ideal for applications that require high voltage measurement such as in car battery applications. Moreover, the IC has a built-in source necessary for the peripheral circuits. Booting and monitoring of the system can be achieved easily with the combination of microcomputer.
