在PCB打样过程中,层叠结构的设计是至关重要的环节。它不仅关系到PCB的性能和稳定性,还直接影响到生产成本和制造周期。本文将从PCB的两个重要组成部分Core和Prepreg(半固态片,简称PP)出发,深入探讨PCB多层板的层叠结构设计的先决条件。
The EVLSPIN32G4-ACT edge AI motor drive reference design simplifies the creation of smart actuators. This design is based on the STSPIN32G4, a 3-phase motor driver for advanced motor control systems. It is designed to work with ST's STWIN.box (STEVAL-STWINBX1), a wireless industrial sensor node, to fast-track the development of systems that merge precise motor control with real-time environmental data analysis and IoT connectivity.
The EVLDRIVE101-HPD (High Power Density) motor-drive reference design packs a 3-phase gate driver, STM32G0 microcontroller, and 750W power stage on a circular PCB just 50mm in diameter. The board features extremely low power consumption in sleep mode, below 1uA, and its tiny outline can fit directly in equipment like hairdryers, handheld vacuums, power tools, and fans. It also fits easily into drones, robots, and drives for industrial equipment such as pumps and process-automation systems.
ST’s STSPIN32 drivers combine a general-purpose STM32 microcontroller (MCU) with a feature-rich three-phase gate driver to simplify design, save PCB area and accelerate time to market. The eight new STSPIN32G0 devices contain gate drivers rated 45V, 250V and 600V, targeting applications from battery-operated appliances and power tools to industrial automation, robots, HVAC systems and line-powered home appliances.
The EVLSERVO1 servo driver reference design from STMicroelectronics offers a highly compact solution specifically engineered for high-power motor-control applications, providing designers with a turnkey platform to explore, develop, and prototype without compromises.
Accelerating development of compact and reliable fans and pumps built with energy-efficient motors, STMicroelectronics has introduced the PWD5T60 three-phase driver with a ready-to-use evaluation board that supports flexible control strategies.
The EVLIOL4LSV1 board leverages ST’s L6364Q dual-channel IO-Link transceiver to handle communications and the IPS4260L intelligent low-side power switch for driving the indicator lights. The board can be directly connected to signaling systems such as smart tower lights used in factory automation, funnel material alarms for quantity-remaining or urgency-level awareness, and other system warnings. It also provides a fast way to test the IPS4260L and L6364Q ICs and has a 4-pin M12 connector for an IO-LINK master and a 5-pin SWD connector for programming.
STMicroelectronics’ IPS4140HQ and IPS4140HQ-1 are richly featured four-channel intelligent power switches, combining a compact 8 mm x 6 mm footprint, 80mΩ RDS(on) (max.) per channel, and 10.5V-36V operating range with extensive diagnostic and protection features.
The TSZ151 op amps have very low offset voltage with minimal temperature drift, offering high accuracy and stability to circuits for sensor interfacing, signal conditioning, and current measurement.
The STPMIC25 power-management IC for STM32MP2 microprocessors is now available, with 16 channels to supply all the MPU power rails as well as system peripherals in one convenient package. Completing the hardware design requires only a small number of external components to provide filtering and stabilization and the STEVAL-PMIC25V1 evaluation board is available now to start development immediately.
TS3121 and TS3121A rail-to-rail, open-drain, single channel comparators feature a novel failsafe architecture and guaranteed start-up time that simplify powering up for short periods to minimize consumption in low-power applications. Ideal for use in industrial controls, building automation, power tools, smart metering, as well as in automotive powertrain and body-control modules.
ST’s DCP3601 miniature monolithic buck converter combines extensive feature integration and flexibility, enabling simple, low-BOM designs to achieve high conversion efficiency. The power switches and compensation are built-in, requiring only six components to complete the circuit, including the inductor, bootstrap and filter capacitors, and feedback resistors for setting the output voltage.
