Ideal Diode and Hot Swap Controller
Enables Supply Redundancy and Isolates Faults
Chew Lye Huat Schottky diodes are used in a variety of ways
to implement multisource power systems.
For instance, high availability electronic
systemsвЂ”such as ВµTCA network and storage
serversвЂ”employ power Schottky diode-OR
circuits in redundant power systems. Diode
ORing is also used in systems with alternate
power sources, such as an AC wall adapter
and a backup battery feed. The problem is that
the Schottky diodes consume power due to
the forward voltage dropвЂ”the resulting heat
must be dissipated with dedicated copper
area on the PCB, or by heat sinks bolted to the
diode, both of which require significant space.
The family of products comprising the
LTC4225, LTC4227 and LTC4228 minimize
power loss by using external N-channel
MOSFETs for pass elements, minimizing the voltage drop from the supply to
the load when the MOSFETs are turned
on. When an input source voltage drops
below the output common supply voltage, the appropriate MOSFET is turned …
