Positive High Voltage Ideal Diode-OR with Input Supply and Fuse Monitors
DESCRIPTION
The LTC®4355 is a positive voltage ideal diode-OR controller that drives two external N-channel MOSFETs. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and PC board area.
FEATURES
Replaces Power Schottky Diodes
Controls N-Channel MOSFETs
0.3μs Turn-Off Time Limits Peak Fault Current
Wide Operating Voltage Range: 9V to 80V
Smooth Switchover without Oscillation
No Reverse DC Current
Monitors VIN, Fuse, and MOSFET Diode
Available in 14-Lead 4mm × 3mm DFN, 16-Lead MS and SO Packages
APPLICATIONS
High Availability Systems
AdvancedTCA® ATCA Systems
+48V and –48V Distributed Power Systems
