PM6613NTR

Overview

The PM6613NTR is a high-efficiency battery charger designed for mobile PC applications, supporting 2 to 4-series Li-Ion or LiFePO4 cells. It features an SMBus communication interface for setting charge current and voltage. The device integrates a synchronous switching DC-DC converter with N-channel high-side and low-side Power MOSFET drivers. It includes two charge pumps to drive N-channel BATFET and ACFET-RBFET MOSFETs. The AC adapter input voltage range is 9 V to 24 V, with a 5 V bias supply. Charge voltage accuracy is ±0.5%, and resolution is 0.1%. It operates in a 16-pin, 3x3 mm QFN package.
