SAN FRANCISCO -- Microchip Technology Inc. today announced its entry into the chip market for stand-alone battery chargers with a new series of ICs.
In a product launch prior to the opening of the Embedded Systems Conference here, Microchip rolled out three lithium-ion battery charger ICs with features that address a variety of battery configurations and self-charging packs.
The Chandler, Ariz.-based company said its ICs contain unique features that will maximize battery operating life, reduce printed-circuit board area, and reduce overall system costs.
"Microchip designed the MCP7382X family, which represents yet another building block in our burgeoning analog portfolio that address portable applications, to drive deep into the battery-management market," said George Paparrizos, product marketing manager for the Analog and Interface Product Division at Microchip.
The MCP73826 is housed in a small SOT-23 package enabling designers to save footprint, where board space is at a premium. The MCP73827 chip has the ability to monitor charge current and to indicate a constant-current to constant-voltage transition by powering up an LED indicator, said Microchip. Meanwhile, the MCP73828 has the ability to monitor temperature and prevent charging when actual temperature is outside operating range.
The devices are available in both 4.1- and 4.2-volt options to accommodate Li-Ion batteries with coke or graphite anodes, Microchip said. The battery chargers feature low shutdown (1 microamp) and operating current (250 microamp) to extend battery life and improving system efficiency.
In quantities of 1,000, the MCP73826 is priced at $0.95 each for the MCP73826. The MCP73827 costs $1.02 each, while MCP73828 is priced at $1.05 each in quantities of 1,000. Samples and volume shipments are now available.
