As device form factors shrink, the heat challenge is growing for motor control applications. Circuit boards are increasingly mounted in high-temperature locations in industrial machinery and office equipment, as well as in household appliances that handle hot air and hot water. In the case of household appliances, such as dishwashers or induction cooktops, in particular, the demand for designs with larger internal capacity or heating areas is increasing, which restricts the space available for circuit boards. The resulting shift toward circuit board designs with smaller surface areas addresses space limitations but also reduces the board's ability to dissipate heat, causing the circuit board itself to get quite hot. To meet these application needs, Renesas is adding new high-temperature-tolerant products to its line of MCUs that can operate in high-temperature spaces and on hot circuit boards. The new devices will provide greater flexibility for product designers working in high-temperature environments, furthering the trend toward more compact devices.
The software can be developed using the RX24T and RX24U CPU cards combined with the 24V motor control evaluation kit, which allows developers to create motor control applications in less time.
