Other Parts Discussed in Thread: BQ25570,
Tool/software:
We are designing an iBOX for a large marine container customer. The product is powered by solar photovoltaic panels and nickel-metal-hydride rechargeable batteries, and it also needs to have an external charging port for emergency situations. Currently, the input voltage of the charging PMIC chip we are using is between 2.7V and 6.5V, and the device's standby current is 75uA at 5.5V. It needs to maintain charging under weak light conditions (when the photovoltaic panel output power is 1mW). After reviewing the BQ25505 and BQ25570 data sheets, we want to know which one is more suitable. If there are other suitable options, please recommend them as well. Additionally, are there any other types of chips or overall solutions that can be recommended for this type of application?
Is there an total solution for this iBOX that you can recommend?
