基于STSPIN32的插件原型板，用于在无绳家庭和花园电动工具中控制3阶段无刷电动机
Based on the highly integratedSTSPIN32 motor-control System in Package,STMicroelectronics has introducedSteval-ptool1v1and STEVAL-PTOOL2V1,two new plug-and-play boards forcontrolling 3-phase brushless motorspowered by up to56V Li-ion batteriesin cordless home and garden power tools.
With a footprint of70毫米x 30毫米,the STEVAL-PTOOL1V1 is suitable for equipment powered by7.4V- to 22.2V Li-ion battery packs和continuous current up to 15Aand standby current less than1µA. The STEVAL-PTOOL1V1 is supported by the STSPIN32F0B motor controller, which contains an STM32F0* microcontroller,3-phase half-bridge gate driver, 12V and 3.3V voltage regulators, an op-amp for current sensing.The device also offers various power stage protection features such as programmable over-current protection (OCP), cross-conduction prevention, and under-voltage lockout (UVLO).
The STEVAL-PTOOL2V1 is suitable for equipment with a battery size of29.6V to 55.5Vand delivers up to19A continuous current. The device is controlled by the STSPIN32F0252 motor controller, which contains a3-phase 250V gate driver, an STM32F0 microcontroller, anda comparatordesigned to offer very fast and flexible OCP. Within the boardfootprint of 77 mm x 54 mm, the device features an onboard bus voltage sensing and offers enhanced reliability of power tools.
Both the boards feature a potentiometer for speed variation, inputs for trigger and rotation-direction setting, thermal shutdown, and protection against reverse biasing of power-stage outputs. The STEVAL-PTOOL1V1 priced at $41.00 and STEVAL-PTOOL2V1 priced at $69.00 are available now.
