Product Summary

The MAX17005BETP is a high-frequency multichemistry battery charger. The circuit features a new high-frequency current-mode architecture that significantly reduces component size and cost. The MAX17005BETP uses a high-side MOSFET with n-channel synchronous rectifier. Widely adjustable charge current, charge voltage, and input current limit simplify the construction of highly accurate and efficient charger. 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 current-sense amplifiers provide fast cycle-by-cycle current-mode control to protect against short circuits to the battery and respond quickly to system load transients. In addition, the MAX17005BETP provides a high-accuracy analog output that is proportional to the adapter current. In the MAX17015B, this current monitor remains active when the adapter is absent to monitor battery discharge current.
