Overview
Description
The ISL9519CEVAL1Z evaluation board is used to evaluate the ISL9519C narrow VDC regulator/charger with SMBus interface. This evaluation board includes a USB to SMBus interface to allow users to control the ISL9519 from a personal computer.
The ISL9519 is a highly integrated battery charger controller for Li-ion/Li-ion polymer batteries with SMBus interface controlling system voltage, charge current and input current limiting.
The ISL9519CEVAL1Z board battery charger control IC contains the N-Channel MOSFETs that drive the synchronous buck converter inductor.
