The Melexis MLX80339 fan driver is designed to provide environment friendly, low-noise motor management. That includes pre-validated logic configurable by way of an intuitive interface, the code-free MLX80339 allows speedy deployment of BLDC motor management with out the overhead of software program improvement.<\/p>\n

\"MelexisEntry-level options for sensorless motor techniques within the shopper, industrial and automotive markets primarily based on single-coil drivers stay well-liked on account of their low price, however they will compromise effectivity and noise efficiency, mentioned Melexis. Three-phase options ship superior outcomes but have historically required advanced integration and longer improvement cycles, it added.<\/p>\n

As a part of Melexis<\/a>\u2019 rising household of code-free IC options, the MLX80339 embeds configurable motor management logic instantly on-chip, permitting engineers to configure and design their utility with out specialised experience.<\/p>\n

The code-free configuration and supporting Begin-to-Run software drastically shorten motor driver prototyping, permitting designs to be operational in lower than quarter-hour when used with the analysis package and Melexis Compact Grasp. This ecosystem generates the required configuration parameters for sturdy motor startup and operation, changing important engineering duties with easy person inputs. Because the motor behaviour logic is pre-characterised and validated by Melexis, engineers want perform solely last application-specific system validation, additional expediting time to market, claimed the corporate.<\/p>\n

Designed for sensorless and quiet operation, the MLX80339 helps management as much as 20W at 12V and 40W at 24V, with a configurable present restrict as much as 3A and built-in under- and overvoltage, overcurrent, and over-temperature safety. The compact SO8-EP bundle is optimised for small fan purposes corresponding to cooling followers, ceiling followers and automotive seat air flow, whereas additionally overlaying small motors, actuators, pumps and associated techniques. It has a large provide voltage vary of 6V to 26V and an working temperature vary of \u221240\u00b0C to 125\u00b0C, with junction temperatures as much as 150\u00b0C.<\/p>\n

The MLX80339 helps legacy PWM-based fan management for easy drop-in substitute, whereas additionally providing digital interfaces corresponding to UART and I\u00b2C for purchasers who require further diagnostics or multi-fan co-ordination. This permits designers to undertake extra superior management ideas the place wanted with out sacrificing simplicity for mainstream designs.<\/p>\n

\u201cWith the MLX80339, we’re making three-phase fan management accessible far past conventional knowledgeable customers,\u201d mentioned Marc Lambrechts, product line director at Melexis. \u201cThe mix of pre-validated motor management logic, quick code-free setup, and high-quality efficiency allows engineers to maneuver shortly whereas delivering cost-effective, quieter, and extra environment friendly finish merchandise. It is a key step in increasing extra subtle motor management to a lot broader markets.\u201d<\/p>\n

By comprehensively eradicating system complexity, the MLX80339 additionally allows entry by new distribution channels and helps lower-volume tasks that had been beforehand impractical with three-phase embedded motor drivers.<\/p>\n

The MLX80339 for small fan management is now accessible for sampling and quantity manufacturing in the usual SO8-EP bundle.<\/p>\n
