Programmable 500-mA Battery Charger Saves Space

Described as the industry’s smallest 500-mA battery charger, the SMB2392 measures 1 mm x 1.3 mm in an eight-ball, lead-free chip-scale package with a 0.5-mm ball pitch and an operating temperature range from -30?C to +85?C. The device requires just two external components and battery charging parameters are fully programmable via its I2C interface and nonvolatile memory, enabling a fully programmable algorithm for single-cell Li-Ion and Li-Polymer cells. All charging parameters, i.e., pre-charge, fast-charge, charge termination current, cell float and pre-charge voltage, battery temperature and timer safety limits, are configurable via the I²C and SMBus interface. Price for the SMB239 is $0.81 each/10,000. SUMMIT MICROELECTRONICS, Sunnyvale, CA. (408) 523-1000.
