The humidifier MOSFET solution focuses on the characteristic requirements of different load scenarios of the whole machine, providing a highly adaptable solution covering the entire chain of atomization drive, power control, and power management, balancing high efficiency, quietness, high reliability, and small size design requirements.

General principles for core selection
‌Margin design:For 12V/24V systems, MOSFET withstand voltage needs to reserve ≥ 50% margin, and the continuous operating current should not exceed 60%~70% of the device's nominal value, to cope with switch spikes and inductive load backlash.
‌Low loss priority:Prioritize devices with low on resistance Rds (on) and low gate charge Qg, while reducing conduction and switching losses and minimizing overall heat generation.
‌Packaging adaptation:High power scenarios use DFN series packaging to ensure heat dissipation, while low-power control circuits use micro packages such as SOT and SC70 to maximize PCB space savings.
‌Environmental reliability:Focus on the working junction temperature range and ESD anti-static ability of the device, and adapt to the long-term continuous operation of humidifiers.
