Maxim Integrated's 12/16-Channel Analog Front-Ends (AFEs) Double Accuracy While Reducing Battery-Management Systems Cost by up to 35%

High-accuracy AFEs integrate simultaneous cell voltage sampling to improve state-of-charge prediction and maximize battery pack longevity.

SAN JOSE, Calif., April 24, 2013 — (PRNewswire) —  Maxim Integrated Products, Inc. (NASDAQ: MXIM) announced it is sampling the MAX14920/MAX14921, high-accuracy, 12/16-channel cell-measurement analog front-ends ( AFEs) that lower battery-management electronics costs by up to 35%. These devices double the accuracy of cell voltage readings through the use of high-accuracy common-mode level shifting and an integrated high-precision amplifier that simplifies ADC data conversion.

Higher accuracy improves state-of-charge determination and cell balancing that in turn lengthen the life of rechargeable Lithium-ion (Li+) battery packs and maximize available energy, especially important for modern battery chemistries that exhibit flat voltage discharge curves, such as those with LiFePO4 cathodes. The MAX14920/MAX14921 enable the industry's highest accuracy cell voltage measurements (±0.5mV, max). Ideal for 48V to 65V pack voltages required in uninterruptible power-supply (UPS) systems, smart grid energy-storage packs, and telecom power backup-battery packs, the MAX14921 eliminates up to two 6-channel AFEs required for 13S-16S channel battery packs.
