1 / 24 page General Description The MAX17005/MAX17006/MAX17015 are high-frequen- cy multichemistry battery chargers. These circuits fea- ture a new high-frequency current-mode architecture that significantly reduces component size and cost*. The charger uses a high-side MOSFET with n-channel synchronous rectifier. Widely adjustable charge current, charge voltage, and input current limit simplify the con- struction of highly accurate and efficient chargers. The charge voltage and charge current are set with analog control inputs. The charge current setting can also be adjusted with a PWM input. High-accuracy cur- rent-sense amplifiers provide fast cycle-by-cycle cur- rent-mode control to protect against short circuits to the battery and respond quickly to system load transients. In addition, the charger provides a high-accuracy ana- log output that is proportional to the adapter current. In the MAX17015, this current monitor remains active when the adapter is absent to monitor battery dis- charge current. The MAX17005 charges three or four Li+ series cells, and the MAX17006 charges two or three Li+ series cells. The MAX17015 adjusts the charge voltage setting and the number of cells through a feedback resistor- divider from the output. All variants of the charger can provide at least 4A of charge current with a 10m Ω sense resistor. The charger utilizes a charge pump to control an n-channel adapter selection switch. The charge pump remains active even when the charger is off. When the adapter is absent, a p-channel MOSFET selects the battery. The MAX17005/MAX17006/MAX17015 are available in a small, 4mm x 4mm x 0.8mm 20-pin, lead-free TQFN package. An evaluation kit is available to reduce design time.
