STMicroelectronics released the STSPIN32G0 series—a system-in-package combining microcontroller, gate driver, and power management for three-phase brushless DC motors. The integration cuts component count and board space versus discrete implementations.
Core specs: Arm Cortex-M0+ at 64 MHz, 64KB flash, 8KB SRAM. Supports field-oriented control and six-step sensorless algorithms. Hardware includes parity checks on SRAM and read/write protection for flash.
Integrated DC-DC buck converter generates 3.3V for logic; separate linear regulator handles gate drivers. Triple half-bridge driver delivers 600 mA source/sink current with interlocking protection.
Operating range: 6.7V to 45V input, -40°C to +125°C. Features 23 GPIO pins, 12-bit ADC with 11 channels, five synchronizable timers, and three rail-to-rail op-amps for current sensing.
Target applications: battery tools, portable vacuums, e-bikes, lawn equipment, industrial automation. The system-in-package format suits space-constrained designs.
