MCP73837-FJI/UN Overview
There is a package called Tube that contains this item.There is currently a package available named 10-TFSOP, 10-MSOP (0.118, 3.00mm Width).There is a type of mounting for this device: Surface Mount.Setting the temperature to -40°C~85°C TA is the right thing to do.A analog IC of POWER SUPPLY SUPPORT CIRCUIT has been used in the design of this device.Constant - Programmable current is required to charge the device.According to the base part number MCP73837, its related parts can be found.I have found that the number of terminations found in it as a whole is 10.For the battery pack, it is 4.2V.According to the specifications, it should be rated at 1.1A when charging at maximum power.This product requires that a total of 10 pins be connected in order for it to work correctly.It is possible to use a total of 1 channels.A 5.2V battery should be sufficient.In order for the device to operate properly, the supply voltage should not exceed 6V.The possibility of optimal efficiency exists if 4.5V output voltage is used as the output voltage.Operation is done using a 1.2A output current.Using a supply voltage as low as 3.75V will allow it to function.A mounting requires that it align itself with Surface Mount.It is required that a maximum supply voltage of 4.523V be applied as the output voltage for this operation.The maximum output current is reduced to 100mA in order to meet the operation conditions.
