                                                LTC4421HUHE#PBF Overview
The case is made of 36-WFQFN Exposed Pad plastic. Tube cases are suitable for packing the part. I would like to point out that the part is mounted in the way of Surface Mount. The voltage that is applied to the circuit is 3V~36V. It is not allowed for this component to operate below -40°C~125°C TA degrees. It fits the Battery Backup, Industrial-connected component. As far as the device classification is concerned, it falls under the N+1 ORing Controller category. A N-Channel-type FET can be identified. The purpose of this is to run the supply current for the part at 530μA in order to run it correctly.
