STMicroelectronics has expanded its STSPIN32 programmable motor controller family with a system-in-package brushless-dc (BLDC) motor battery-operated power tools. STSPIN32F0B as it will be known integrates an op-amp for current sensing through a single resistor in the negative return wire (diagram below. On-board is a 48MHz STM32F031x6 MCU (Arm Cortex-M0 core) capable of running a six-step ...
