Function : Two-Supply Diode-OR Current Balancing Controller / 16-Lead DFN (4mm × 3mm) and MSOP Packages
Maker : Linear Technology
The LTC4370 is a two-supply current sharing controller which incorporates MOSFET ideal diodes. The diodes block reverse and shoot-through currents during start-up and fault conditions. Their forward voltage is adjusted to share the load currents between supplies. Unlike other sharing methods, neither a share bus nor trim pins on the supply are required.
The maximum MOSFET voltage drop can be set with a resistor. A fast gate turn-on reduces the load voltage droop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse current transients.
The controller operates with supplies from2.9V to18V. For lower rail voltages, an external supply is needed at the VCCpin. Enable inputs can be used to turn off the MOSFET and put the controller in a low current state. Status outputs indicate whether the MOSFETs are on or off. The load sharing function can be disabled to turn the LTC4370 into a dual ideal diode controller.
