Full-Bridge 600V/3.5A Power Driver Features SiP Format

STMicroelectronics’ has released its PWD5F60 high-density power driver, the second in a new series of power-driver systems-in-package addressing high-voltage brushed DC and single-phase brushless motor applications. It integrates a 600V/3.5A single-phase MOSFET bridge with gate drivers, bootstrap diodes, protection features, and two comparators in a 15 mm x 7 mm outline. The thermally efficient system-in-package occupies 60% less board real-estate than discrete components, while boosting reliability and simplifying design and assembly.

As a single-phase full-bridge module, the PWD5F60 is tailored for driving brushed DC motors in applications such as industrial pumps and fans, blowers, domestic appliances, and factory-automation systems. It is particularly targeted at the appliances using single-phase brushless motors that guarantee high durability and efficiency at a reasonable cost. It is also cost-effective and convenient for use in power supply units.

With on-resistance of 1.3 8Ω, the PWD5F60’s integrated N-channel MOSFETs ensure high efficiency for handling medium-power loads. The gate drivers are optimized for reliable switching and low EMI (electromagnetic interference), while the integrated bootstrap diodes enable high-voltage startup with no need for external diodes and passive components to supply the high-side inputs.

Flexibility is assured by two embedded uncommitted comparators that allow an easy implementation of peak current control or over-current and over-temperature protection features. The peak-current control used in conjunction with positioning Hall-effect sensors allows to achieve a stand-alone controller with no need of a dedicated MCU and hence drastically reducing the cost of control electronics. Further flexible features include adjustable dead-time and the option to configure the MOSFETs as a single full bridge or two half bridges. Operating voltage range extends from 10 V to 20 V and inputs are compatible with 3.3 V-15 V control signals to ease interfacing with Hall sensors or a host microcontroller or DSP

Cross-conduction prevention and under-voltage lockout are already built-in to protect the device by preventing operation in low-efficiency or dangerous conditions. The PWD5F60 is in production and available now, packaged as a multi-island VFQFPN device, from $2.15 for orders of 1,000 pieces.

MPU-Based SOM Meets Industrial IoT Linux Needs

Microchip Technology has unveiled a new System on Module (SOM) featuring the SAMA5D2 microprocessor (MPU). The ATSAMA5D27-SOM1 contains the recently released ATSAMA5D27C-D1G-CU System in Package (SiP). The SOM simplifies IoT design by integrating the power management, non-volatile boot memory, Ethernet PHY and high-speed DDR2 memory onto a small, single-sided printed circuit board (PCB). There is a great deal of design effort and complexity associated with creating an industrial-grade MPU-based system running a Linux operating system. Even developers with expertise in the area spend a lot of time on PCB layout to guarantee signal integrity for the high-speed interfaces to DDR memory and PHY while complying with EMC standards.

The SAMA5D2 family of products provides an extremely flexible design experience no matter the level of expertise. For example, the SOM—which integrates multiple external components and eliminates key design challenges around EMI, ESD and signal integrity—can be used to expedite development time. Customers can solder the SOM to their board and take it to production, or it can be used as a reference design along with the free schematics, design and Gerber files and complete bill of materials which are available online. Customers can also transition from the SOM to the SiP or the MPU itself, depending on their design needs. All products are backed by Microchip’s customer-driven obsolescence policy which ensures availability to customers for as long as needed.

The Arm Cortex-A5-based SAMA5D2 SiP, mounted on the SOM PCB or available separately, integrates 1 Gbit of DDR2 memory, further simplifying the design by removing the high- speed memory interface constraints from the PCB. The impedance matching is done in the package, not manually during development, so the system will function properly at normal and low- speed operation. Three DDR2 memory sizes (128 Mb, 512 Mb and 1 Gb) are available for the SAMA5D2 SiP and optimized for bare metal, RTOS and Linux implementations.

Microchip customers developing Linux-based applications have access to the largest set of device drivers, middleware and application layers for the embedded market at no charge. All of Microchip’s Linux development code for the SiP and SOM are mainlined in the Linux communities. This results in solutions where customers can connect external devices, for which drivers are mainlined, to the SOM and SIP with minimal software development.

The SAMA5D2 family features the highest levels of security in the industry, including PCI compliance, providing an excellent platform for customers to create secured designs. With integrated Arm TrustZone and capabilities for tamper detection, secure data and program storage, hardware encryption engine, secure boot and more, customers can work with Microchip’s security experts to evaluate their security needs and implement the level of protection that’s right for their design. The SAMA5D2 SOM also contains Microchip’s QSPI NOR Flash memory, a Power Management Integrated Circuit (PMIC), an Ethernet PHY and serial EEPROM memory with a Media Access Control (MAC) address to expand design options.

The SOM1-EK1 development board provides a convenient evaluation platform for both the SOM and the SiP. A free Board Support Package (BSP) includes the Linux kernel and drivers for the MPU peripherals and integrated circuits on the SOM. Schematics and Gerber files for the SOM are also available.

The ATSAMA5D2 SiP is available in four variants starting with the ATSAMA5D225C-D1M- CU in a 196-lead BGA package for $8.62 each in 10,000 units. The ATSAMA5D27-SOM1 is available now for $39.00 each in 100 units The ATSAMA5D27-SOM1-EK1 development board is available for $245.00.
