Other Parts Discussed in Thread: LM74700-Q1 , TPS2419 , LM5051 , TPS2413 Hello, My customer looking for N+1 and ORing power rail controller devices. Their requirements are as following two cases. #1 V=-48V(typ)/-65V(min) I=>10A Hot swap, OCP and EN support…
Hi Stan
0.22uF cap of G/S of MOSFET is huge.
Removing it will definitely help to increase the turn on time of V5A gate.
If you are not requiring current sharing, TPS2413 will perform better here than TPS2412.
TPS2412 regulates the Vds of MOSFET…
Hi Eagle Miao,
TPS2413 targets high current 12V rail ORing application.
200A would require large MOSFETs in parallel which will have large gate capacitance.
TPS2413 has about 300uA of gate drive current.
Based on the gate drive current and gate…
Hello Frederic,
Well, not exactly. Dual ORing controller also may not solve the problem unless you can detect the reverse current close to 0-A.
TPS2412/TPS2413 has programmable reverse current which can be set to positive also (Reverse turn off at…
Hello Wei-Hao Chen,
For 250A customers use multiple FETs in parallel to share the load current and power dissipation.
Is the customer using multiple FETs here?
If the operating voltage is lower than 16V and close to 12V, TPS2413 or TPS2411 which…
Hi
Vgs is controlled by the LM5050 in order to regulate Vds of MOSFET to 22mV.
So, gate voltage will not be fully enhanced.
If you would require a device that does not do regulation of Vds, please have a loop at TPS2413 device.
This can work up…
Anil,
I am not aware of any powerpath chargers that can have their SYS pins tied together without using (ideal) diodes in OR configuration to prevent current back flow from on charger SYS output to the other. TI makes ideal diode ORing controllers …
