Description

The SAA1501T is intended to be used as a battery monitor and charge current control circuit in rechargeable battery
systems.

The SAA1501T is processed in BiCMOS technology where the benefits of mixed bipolar and CMOS technology is fully utilized to achieve high accuracy measurements and digital signal processing in the same device. The general function of the integrated circuit SAA1501T is a Coulomb counter. During battery charging, the charge current and charge time are registered in a Coulomb counter. During discharge, the discharge current and time are recorded. The momentary charge amount of the batteries can be displayed either on an LCD screen or on an LED bargraph. Using the SAA1501T, intelligent batteries or intelligent battery powered systems can be easily designed with only a few external components.
