Single-Chip with Integrated Microcontroller and MOSFET Gate Driver
All-in-One Device Implementation for 4.5V~18V Motor Control Applications

NXP Semiconductors has announced the MC9S08SUx microcontroller (MCU) product family, the world's smallest single-chip SoC solution. This product features an integrated 18V-to-5V LDO (Low Drop Out) and MOSFET gate driver, providing ultra-high-voltage solutions for motor control applications such as drones, robots, and power tools. With a voltage range of 4.5V to 18V, it implements reliability integrated with low bill-of-materials (BOM) costs. The SoC solution meets the demand to reduce cost and size under space constraints and replace multiple components with a single MCU for simplified layout.

An NXP representative stated, "With a 4x4x0.65mm structured form factor that reduces PCB size by half, we are the only company in the industry to offer a single-chip product integrating both microcontroller and MOSFET gate driver."

Additionally, the single chip implements an all-in-one device by utilizing a central processing unit with an integrated gate driver for three-phase MOSFET 4.5V~18V motor control applications. It eliminates the need for separate LDO voltage regulators, operational amplifiers, and gate drivers, reducing costs. Furthermore, NXP has integrated virtually all necessary functions—including zero-crossing detection, pulse-width measurement, overvoltage protection, and overcurrent protection—into BLDC motor control, so developers only need to configure registers.

NXP's S08 microcontroller, including the newly launched MC9S08SUx product family, is supported by CodeWarrior IDE. FreeMASTER support is provided as a runtime debugging tool. Additionally, since IAR Embedded Workbench supports NXP's S08 MCU portfolio, it provides a single toolbox complete with configuration files, code examples, and project templates.

A product manager at IAR Systems stated, "The leading optimization technology of IAR Embedded Workbench helps developers maximize performance and minimize power consumption based on NXP's newly launched product family."
