MAX1909ETI+ Overview

There is a package for Tube in which it can be found.Among the packages that come with this product, there is one that is 28-WFQFN Exposed Pad.There is a mounting type Surface Mount specified for the device.The correct temperature setting is -40°C~85°C TA.In order for this device to function, it utilizes an analog integrated circuit called POWER SUPPLY SUPPORT CIRCUIT.To charge the device, a current of Constant - Programmable is required.There are related parts for this device under the base part number MAX1909.As far as the terminations are concerned, there are 28.In the battery pack, the voltage is 17.65V Max.It has a total of 28 pins on it.For it to work, 28 pins are required.The number of channels available is 2.The device should operate on a 18VV battery.In the case of a 17.65V output voltage, high efficiency is possible.It is in this instance that the device's output current is set to 4A.There is one subcategory of this device, and it is Power Management Circuits.As far as the mounting is concerned, it is mounted in the way of Surface Mount.It was determined during the design process that Vsup (maximum supply voltage) should be set to 6mA.The supply of the gadget is running with 2.7mA current.As a rule of thumb, the supply voltage needs to be set to 28V for optimum efficiency.During normal operation, Vsup should remain above 8V.
