Three-Phase Brushless DC Companion Device Enables Microchip to Offer Complete, Robust Motor System Solutions

MCP8024 Three-Phase Brushless DC Companion Device Provides All Power, Sensing and Protection Functions Needed to Implement a Robust, Highly Efficient Solution

CHANDLER, Ariz.--Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced a new three-phase BLDC motor gate driver with power module, the MCP8024. This new device includes functions that power dsPIC® Digital Signal Controllers (DSCs) and PIC® microcontrollers (MCUs) with capabilities to drive six N-channel MOSFETs. Customers can implement improved performance and high robustness, providing increased efficiency and lowering system cost while reducing time to market.

The MCP8024 operates across a wide voltage range of 6V to 28V and can withstand transient voltage up to 48V. The device provides high-integration analog such as three current-sensing operational amplifiers, an over-current comparator, MOSFET drivers and a bidirectional communication interface for a complete motor system design. The configurable driver dead-time management, driver blanking-time control, and Over-Current Limit (OCL) for external MOSFETs offer a significant increase in flexibility. The adjustable step-down DC-to-DC converter powers a broad range of microcontrollers, with the efficiency benefits of a switch-mode power supply. Additionally, the wide operating temperature range from -40°C to +150°C (H-temp) allows the MCP8024 to be utilized in harsh environments, such as automotive under-hood applications.

The MCP8024 is available in thermally enhanced 40-pin QFN 5mm x 5mm and 48-pin TQFP 7mm x 7 mm packages. The MCP8024 is well suited for a broad range of applications in the automotive market, such as HVAC blowers and pumps, and the industrial market, including fans, motion control and robotics, among others.

"The automotive and industrial markets continue to demand higher performance, higher integration, faster time to market and more flexibility, all in a cost-effective solution," said Bryan J. Liddiard, marketing vice president of Microchip's Analog and Interface Products Division. "The integrated voltage regulators, current sensing amplifiers and over-current protection make the MCP8024 an ideal candidate to use with a broad range of MCUs, DSCs and FPGAs. By combining with dsPIC DSCs and PIC microcontrollers, Microchip can help solve customers' problems and provide complete motor solutions."

Development Support

The MCP8024 is supported by Microchip's MCP8024 TQFP BLDC Motor Driver Evaluation Board (Part # ADM00557, $99.00), which is expected to be available on December 20.

Pricing & Availability

The MCP8024 is available now for sampling and volume production in 40-pin QFN 5mm x 5mm and 48-pin TQFP 7mm x 7mm packages, for $2.61 each, in 10,000-unit quantities.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
