Mouser Electronics is now stocking the MC9S08SU 8-bit microcontroller from NXP Semiconductors. This is a single-chip device for 4.5 V – 18 motor control applications. According to Mouser, it helps lower BOM costs and reduces footprint by up to 50 percent.
The NXP MC9S08SU microcontroller provides up to 16 kbytes of flash memory and 768 bytes of internal RAM. The device’s core includes a three-phase MOSFET pre-drivers unit that supports three high-side p-channel and three low-side n-channel MOSFETs and amplifiers for current measurement and over current and over voltage protection.
The MC9S08SU microcontroller offers new features like a six channel PWM module, two 16-bit pulse width timers, a two-channel flex timer, and a 16-bit module timer. It also has a 5-channel, 12-bit analog-to-digital converters (ADCs) and a three phase analog comparator for sensorless control. It also has a SCI module and an I²C module that supports SMBus interface.
Mouser also stocks the S08SU16-EVK evaluation board. According to Mouser, this board demonstrates a simple control approach to a low-power, three-phase, brushless DC (BLDC) motor drive application using back electromotive force (BEMF) sensing for position recognition.
The microcontroller is available in a 4 mm x 4mm, 24-pin QFN package and operates over a temperature range of -40 to 105 degrees Celsius. The microcontroller can be used in a variety of motor control applications, including BLDC motors, DC fans, healthcare devices, power tools and electronic speed control (ESC) for drones and robotics.
