Abstract: Targeting industrial control cabinets, energy storage devices, and intelligent cooling scenarios for industrial power supplies, the full range of low voltage MOSFETs combined with high-performance DC-DC controllers provide stable and reliable domestic device solutions for temperature control and speed regulation of industrial fans.

Application Overview
Industrial cooling systems are widely used in various industrial equipment such as industrial control cabinets, frequency converters, servo devices, energy storage cabinets, and industrial power supplies. They achieve constant temperature cooling and active cooling through intelligent temperature control fans. Industrial scenarios have large voltage fluctuations, wide environmental temperature differences, and frequent start stop speed regulation of fans, which belong to typical inductive load conditions. They require strict compatibility, stability, shock resistance, and continuous reliability of driving devices. The power MOS and power control chip, as the core components for fan speed regulation, load switching, and system voltage regulation, directly determine the temperature control accuracy, operating noise, and service life of the entire cooling system.
Huaxin Er is oriented towards the industrial heat dissipation field, focusing on the layout of N+N, P+P, N+P all types of medium and low voltage MOSFETs, fully adapting to mainstream driving topologies such as half bridge, full bridge, positive and negative control of industrial heat dissipation fans. The rich combination of tube types can flexibly match the design requirements of different power fans. The devices have the characteristics of low conduction loss, good switch consistency, and excellent anti avalanche performance, effectively improving the problems of unstable speed regulation, shaking, and heating of fans. They can easily cope with frequent start stop and reverse electromotive force impact of inductive loads, ensuring the long-term continuous and stable operation of heat dissipation fans and helping customers achieve domestic replacement of devices.
