Battery chargers cut size and costs
High switching frequency allows the use of smaller passive components, and the option to use N-channel switches reduces costs.
Available now from Maxim Integrated Products, the MAX17005, MAX17006 and MAX17015 high-frequency, multichemistry battery-charger ICs use a proprietary high-frequency current-mode architecture that significantly reduces the cost and size of external components Designed to operate at a 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

Speedy DAC claims dynamic superiority for comms
The MAX5195 is a 14bit 260Msample/s DAC claimed to provide the world's best dynamic performance in spurious-free dynamic range, intermodulation distortion and signal to noise ratio.
Low-power serial ADC runs up to 200Ksample/s
New from Maxim Integrated Products, the MAX1162 serial-interface 16bit A/D convertor connects directly to SPI, QSPI and Microwire devices without additional interface logic.
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 devices.
Saving both space and cost, the MAX17005, MAX17006 and 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 4.2 to 4.4V; the MAX17006 charges two to three cells with a cell voltage of 4.2 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 analogue 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 20mohm sense resistor and overvoltage protection.
The MAX17005, MAX17006 and MAX17015 are available in 4 x 4 x 0.8mm lead-free 20-pin TQFN packages, and are fully specified over the -40 to +85C extended-industrial temperature range.
Prices start at US $5.66 (1000-up).
