Freescale introduces new lithium-ion battery cell controller

Lithium-ion chemistries are increasingly replacing lead-acid automotive batteries, especially in start-stop and energy recuperation systems, and they are even making inroads into starter battery applications. Electronics such as Freescale Semiconductor’s battery cell controllers are used to manage risks such as overcharge, overheating and internal short circuits. Now Freescale has introduced the MC33772 3- to 6-cell… Read more »

Freescale Semiconductor’s new integrated battery cell controller

As some automakers such as Audi are turning to 48 V electrical systems to facilitate the integration of ever more electronic accessories, Austin, Texas-based Freescale Semiconductor (NYSE: FSL) has introduced a highly integrated 14-cell lithium-ion battery cell controller. Freescale’s MC33771 battery cell controller and companion MC33664 isolated communications interface include fourteen cell balancing transistors, a… Read more »

Freescale’s new battery sensor combines MCU and CAN with three-channel analog front end

Freescale Semiconductor (NYSE:FSL) has announced a new battery sensor that it says is the first to combine three measurement channels, a 16/32-bit MCU, and a CAN protocol module in a single package. The MM9Z1J638 battery sensor measures key battery parameters for monitoring state of health (SOH), state of charge (SOC) and state of function (SOF)… Read more »
