MAX17006A Overview
Description
The MAX17005A/MAX17006A/MAX17015A are high-frequency multichemistry battery chargers. These circuits feature a new high-frequency current-mode architecture that significantly reduces component size and cost*.
Key Features
- 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
- The charge voltage and charge current are set with analog control inputs
- The charge current setting can also be adjusted with a PWM input
- In addition, the charger provides a high-accuracy analog output that is proportional to the adapter current
- In the MAX17015A, this current monitor remains active when the adapter is absent to monitor battery discharge current
- The MAX17005A charges three or four Li+ series cells, and the MAX17006A charges two or three Li+ series cells
- The MAX17015A 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 10mΩ sense resistor
- The charger utilizes a charge pump to control an n-channel adapter selection switch
