Infineon IRMCK099 hair dryer solution

This design controls the hair dryer motor and features high efficiency and low noise.

Program overview

 

This scheme design uses Infineon's IRMCK099 microcontroller as the main control chip, and IPM as the power module. This design controls the hair dryer motor and features high efficiency and low noise.

 

Infineon's IRMCK099 is a permanent magnet synchronous motor (PMSM) sensorless field oriented control (FOC) variable speed motor control integrated circuit (IC).

 

IRMCK099 contains a flexible Tiny Motion Control Engine (TinyMCE), without any programming, powerful startup and configuration tools can make the motor run quickly. Internal clock 100MHz, built-in ITRIP comparator, standby low power consumption mode, 3.3V single power supply, working current <30mA, which can realize low-cost/high-performance motor control solutions;

 

Infineon's IPM series has an internal NTC, which can quickly sense the temperature of the module to prevent the module from damaging the op amp. It has a rail-to-rail function to ensure that the current collection has the same width in the positive and negative directions.
