MAX8903AETI+ Overview


I found it in the Tube package, which comes with everything you need.For convenience, it is included in the 28-WFQFN Exposed Pad package.In this case, the device has a mounting type of Surface Mount.Ideally, the temperature should be set to -40°C~85°C TA in order to ensure reliable performance.In order to operate, the device relies on an analog IC named POWER SUPPLY SUPPORT CIRCUIT.To charge the device, there is a requirement for Constant - Programmable current.There are related parts to this device according to the base part number MAX8903.I have found that the number of terminations found in it as a whole is 28.Batteries have a voltage of 4.2V.28 pins are attached to it.Features such as Current, Timer are programmable.The device has a maximum charging current of 2A.It requires pins 28 to function.The system currently provides 1 channels for the user to use.Battery voltage should be 5V.There is a possibility of achieving optimal efficiency when the output voltage of the device is 5V.The operation is carried out with an output current of 1mA.This device is a member of subcategory Power Management Circuits.I'd like to emphasize that the mounting of the device is done in the same manner as Surface Mount.It is set to 4mA for Vsup (maximum supply voltage).The power supply for this part is set to 5V.There are several electrical components in the series Smart Power Selector?.It appears that there is 2.3mA current flowing through the supply of the gadget at the moment.The supply voltage should be set to 16V for best efficiency.To fulfill the operation requirements, the maximum output supply voltage is reduced to 5.4V.There is a reduction in the maximum output current during operation to 500mA.
