JW7201 Datasheet | JoulWatt Technology

DESCRIPTION The JW®7201 is a high-side OR-ing FET controller, which can operate in conjunction with two external MOSFETS as ideal diodes rectifier when connected in series with power sources. Besides, the power consumption, heat dissipation and PC board area also can be reduced by using the diode-OR with N-channel MOSFETS instead of Schottky diodes. Power sources can easily be ORed together to increase total system reliability with the JW7201. The JW7201 controls the voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. There is a fast response parator to turn off the MOSFETS to prevent the reverse current from reaching a level that could damage the MOSFET if a power source fails or is shorted. of the external N-channel gate drive(VGSx) are less than 0.6V, or the voltages across the MOSFETS are greater than the fault threshold will trigger the power fault detection. FEATURES - Replaces power schottky diodes - Controls N-channel MOSFETS - 0.3µs turn-off time limits peak fault current - Wide operating voltage range: 6V 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 SOP packages APPLICATIONS Fault conditions such as the input supplies are not in regulation, the inline fuses are blown, both pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joul Watt technology Inc. - High Availability Systems - Advanced TCA® (ATCA) Systems - +48V and - 48V Distributed Power Systems - Tele Infrastructure TYPICAL APPLICATION VIN1=+48V VIN2=+48V 340K 12.7K GND +48V Diode-OR 7A N-MOSFET F1 7A N-MOSFET F2 340K 12.7K IN1 GATE1 IN2 GATE2 MON1 MON2 GND OUT VGSFLT FUSEFLT1 FUSEFLT2 PWRFLT1 PWRFLT2 TO LOAD 22K 22K 22K 22K 22K JW7201 Rev.0.2...
