MAX77818EWZ+ Product Details

MAX77818EWZ+ Overview


The package Strip contains it, and you can find it there.The package that is included with it comes in the shape of a 72-WFBGA, WLBGA.Amounting type Surface Mount is the one associated with the device.The best thing to do is to set the temperature to -40°C~85°C TA.To operate the device, an analog IC called POWER SUPPLY MANAGEMENT CIRCUIT is used.Charge the device by providing it with Constant - Programmable current.Based on the base part number MAX77818, it is possible to find related parts for this device.I have found that the number of terminations found in it as a whole is 72.It is a 4.2V voltage for the battery pack.On the device, there is 3A maximum charging current listed.Currently, there are a total of 2 channels available for use in the application.In order to run it, you would need a battery with 3.7V.If the supply voltage exceeds 5V, the device will not function properly.It is important to keep the power supply voltage (Vsup) above 2.8V so that normal operation can take place.
