... The LTC4416I is guaranteed and tested over the –40°C to 125°C operating temperature range. Note 3: This results in the same supply current as would be observed with an external P-channel MOSFET connected to the LTC4416 and operating in forward regulation. Note 4: Only permutations illustrated. This specification is the same when power is provided through ...

... If the E2 signal is driven high, the V2 path will perform a “soft-off” provided the PFET(s) are properly configured for blocking DC current. An internal current sink will pull the E2 pin down when the E2 input exceeds 1.5V. E2 (Pin 4): LTC4416-1 Comparator Enable Input. A low signal less than V will enable the V2 path. The ideal REF diode action will then determine if the V2 path should turn on by controlling any PFET(s) connected to the G2 pin ...

... OPERATIO U Operation can best be understood by referring to the Block Diagram which illustrates the internal circuit blocks. The LTC4416/LTC4416-1 are divided into three sections, namely: 1. The channel 1 controller consisting of A1, C1, the “first analog contoller,” the G1 drivers and the H1 output driver. 2. The band-gap reference 3. The channel 2 controller consisting of A2, C2, the “ ...

... FON the I current is set LTC4416 OPERATION The interaction of the LTC4416 analog controllers distin- guish the operation of the LTC4416 from a simple circuit using two PowerPath controllers. Table 1 explains the different operation modes of the analog controllers. – V and Table 1. LTC4416 Operational Modes ...

... No electrical harm to the LTC4416 will occur. Channel 2 is Disabled The LTC4416 is not designed to have channel 2 disabled by connecting E2 high and leaving indeterminate state. If this happens, the channel 1 PowerPath controller will not have reverse turn-off capability. No electrical harm to the LTC4416 will occur ...

... Figure 5. Dual PowerPath for Current Sharing LTC4416-1 The LTC4416-1 will support all three of the LTC4416 applications without the “soft-off” feature. The only dif- ference in the two designs is the LTC4416-1 will rapidly switch off the load from a supply whenever a channel disabled ...
