Low Voltage OR-ing FET Controller  
ISL6146  
Features  
The ISL6146 represents a family of OR-ing MOSFET controllers  
capable of OR-ing voltages from 1V to 18V. Together with suitably  
sized N-channel power MOSFETs, the ISL6146 increases power  
distribution efficiency when replacing a power OR-ing diode in high  
current applications. It provides gate drive voltage for the  
MOSFET(s) with a fully integrated charge pump.  
• OR-ing Down to 1V and Up to 20V with ISL6146A, ISL6146B,  
ISL6146D and ISL6146E  
• Programmable Voltage Compliant Operation with ISL6146C  
• VIN Hot Swap Transient Protection Rating to +24V  
• High Speed Comparator Provides Fast <0.3µs Turn-off in  
Response to Shorts on Sourcing Supply  
The ISL6146 allows users to adjust with external resistor(s) the  
V
- V trip point, which adjusts the control sensitivity to system  
OUT IN  
• Fastest Reverse Current Fault Isolation with 6A Turn-off  
Current  
power supply noise. An open drain FAULT pin will indicate if a  
conditional or FET fault has occurred.  
• Very Smooth Switching Transition  
The ISL6146A and ISL6146B are optimized for very low voltage  
operation, down to 1V with an additional independent bias of 3V  
or greater.  
• Internal Charge Pump to Drive N-channel MOSFET  
• User Programmable V - V  
IN OUT  
Vth for Noise Immunity  
The ISL6146C provides a voltage compliant mode of operation  
down to 3V with programmable Undervoltage Lock Out and  
Overvoltage Protection threshold levels  
• Open Drain FAULT Output with Delay  
- Short between any two of the OR-ing FET Terminals  
- GATE Voltage and Excessive FET V  
- Power-Good Indicator (ISL6146C)  
DS  
The ISL6146D and ISL6146E are like the ISL6146A and ISL6146B  
respectively but do not have conduction state reporting via the  
fault output.  
• MSOP and DFN Package Options
