Multichemistry Battery Charge ICs minimize end product size.
Press Release Summary:
Employing high-frequency (1.2 MHz), current-mode architecture, MAX17005, MAX17006, and MAX17015 minimize output filter size requirements and allow use of n-channel power-selection switches. While MAX17005 and MAX17006 respectively charge 3-4 and 2-3 cells with voltages from 4.2-4.4 V, MAX17015 adjusts charge-voltage setting and number of cells through feedback resistor-divider at output. Each device has analog output proportional to adapter current.

o These devices minimize the overall cost and size of charger solutions.
o By utilizing a proprietary, high-frequency, current-mode architecture, these ICs significantly reduce the cost and size of external components.
o The MAX17005/MAX17006/MAX17015 are ideal for multichemistry battery packs such as those used in notebook computers.
SUNNYVALE, CA-May 16, 2008-Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX17005/MAX17006/MAX17015 high-frequency, multichemistry battery-charger ICs. These devices employ a proprietary, high-frequency, current-mode architecture* that significantly reduces the cost and size of external components. Designed to operate at a high, 1.2MHz switching frequency, these ICs enable the use of a smaller output filter than required by many other battery-charger ICs, thus reducing the size of the design and the BOM cost associated with the output filter. Additionally, this family of battery-charger ICs allows the use of n-channel power-selection switches instead of the more expensive p-channel power switches used by conventional solutions. Saving both space and cost, the MAX17005/MAX17006/MAX17015 are ideal for notebook computers, tablet PCs, and other portable devices with rechargeable batteries.
The MAX17005 charges three to four cells with a cell voltage of 4.2V to 4.4V; the MAX17006 charges two to three cells with a cell voltage of 4.2V to 4.4V; and the MAX17015 adjusts the charge-voltage setting and number of cells through a feedback resistor-divider at the output. In addition, these devices provide a high-accuracy analog output that is proportional to the adapter current. In the MAX17015, current monitoring remains active to monitor the battery's discharge current when the adapter is absent. All devices provide at least 4A of charge current with a 20mÃ(TM) sense resistor and overvoltage protection.
The MAX17005/MAX17006/MAX17015 are available in a small, 4mm x 4mm x 0.8mm, lead-free, 20-pin TQFN package and are fully specified over the -40°C to +85°C extended-industrial temperature range. Prices start at $5.66 (1000-up, FOB USA).
