Renesas Electronics Corporation OR Controllers, Ideal Diodes ISL6146CFRZ-TK

The ISL6146CFRZ-TK is a low voltage OR-ing MOSFET controller designed for efficient power distribution in high current applications. It operates with input voltages ranging from 1V to 18V and is capable of replacing traditional power OR-ing diodes. The controller features an integrated charge pump that provides gate drive voltage for external N-channel MOSFETs, enhancing overall power efficiency. This part includes programmable undervoltage lockout (UVLO) and overvoltage protection (OVP) thresholds, allowing for tailored operation in various applications. The device also incorporates a fast comparator for quick turn-off in response to shorts, achieving a turn-off time of less than 0.3µs. An open-drain FAULT pin indicates conditional or FET faults, providing diagnostic capabilities. The ISL6146CFRZ-TK is suitable for applications such as N+1 industrial and telecom power distribution systems, uninterruptible power supplies, and low voltage processors. It is available in both MSOP and DFN package options, facilitating integration into compact designs.
