JW7260
High-side Single ORing Controller
Preliminary Specifications Subject to Change without Notice
DESCRIPTION
The JW®7260 is a positive voltage ideal diode-OR controller that drives an external N-channel MOSFET. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and PC board area.
With the JW7260, power sources can easily be ORed together to increase total system reliability.
In the forward direction the JW7260 controls the voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If a power source fails or is shorted, fast turnoff minimizes reverse current transients.
