Switch-Mode Battery Chargers with Programmable JEITA Support for High System Safety

Mon, 06/21/2010 - 5:27am


Summit Microelectronics has expanded its third-generation programmable battery charger integrated circuit (IC) family for single-cell Li-Ion, Li-Polymer, and Li-FePO4 powered systems. The SMB328A and SMB328B integrate the largest feature set in the industry, including compatibility with all relevant industry standards:  USB 2.0 Specification, USB On-The-Go Supplement, JEITA Safety Guidelines, IEEE1725 Standard, Chinese USB Charging Specification, and others. Both products incorporate innovative functionality that allows automatic matching between the AC/DC adaptor's current capability and the portable device's charging requirements. High-efficiency operation allows for higher, continuous charging current levels, thereby ensuring battery charging even during high system load conditions. Like all Summit's solutions, digital, non-volatile programmability provides design and system flexibility at no additional cost.
