ISL6146BEVAL1Z, Evaluation Board, ISL6146BFUZ, Low Voltage OR-ing FET Controller, Power Management

ISL6146BEVAL1Z is an ISL6146B evaluation board. 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. The ISL6146 allows users to adjust with external resistor(s) the VOUT - VIN trip point, which adjusts the control sensitivity to system power supply noise. An open drain FAULT pin will indicate if a conditional or FET fault has occurred. It is optimized for very low voltage operation, down to 1V with an additional independent bias of 3V or greater.

• Separate BIAS and VIN with active low enable
• OR-ing down to 1V and up to 20V
• VIN hot swap transient protection rating to +24V
• High speed comparator provides fast
• Fastest reverse current fault isolation with 6A turn-off current
• Very smooth switching transition
• Internal charge pump to drive N-channel MOSFET
• User programmable VIN - VOUT Vth for noise immunity
• Open-drain active low FAULT output with delay
