LT4356IDE-2#PBF

LT4356IDE-2#PBF is a dual high-side, current-limited ideal-diode controller from Analog Devices (Linear Technology). It drives two external N‑channel MOSFETs to create two independent “ideal diode” paths with reverse-current blocking and hot-swap protection. Each channel provides adjustable current limit (via a sense resistor), soft-start, enable/disable, undervoltage lockout, and protection against overcurrent and overtemperature. It’s typically used for dual power-path applications such as OR-ing multiple supplies, battery backup, solar/battery charging, and server hot-swapped rails. The “IDE-2” denotes the package/variant, and “#PBF” indicates Pb-free, RoHS-compliant packaging. Because the MOSFETs are external, the device’s voltage and current capability depend on the chosen FETs. For exact pinout, specs, and application guidance, refer to the LT4356 datasheet.
