The ISL9519TQFNEVAL2Z evaluation board is used to evaluate the ISL9519 narrow VDC regulator/charger with SMBus interface. 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 evaluation board includes a USB to SMBus interface to allow users to control the ISL9519 from a personal computer.
ISL9519TQFNEVAL2Z is designed for input voltages below 7V (i.e., 5V input) but has protection from input voltage up to 22V. It differs from the design for input voltages >7V (ISL9519EVAL1Z) in three ways. ISL9519TQFNEVAL2Z drives both input PFETs with AGATE to turn both on when adapter voltage is high. ISL9519EVAL1Z drives SGATE on only when input current is >300mA. ISL9519TQFNEVAL2Z has a circuit that connects input voltage to VDD when the input is less than 5.2V to bypass the internal LDO. ISL9519TQFNEVAL2Z has a zener to protect ADET from voltages >7V absolute maximum if the input voltage is >9.5V.
