By including a fully integrated 110V N/N gate-driver, these new devices integrate a series of gate-drivers to meet different motor product voltage requirements. These new devices include a fully integrated 5V LDO and bootstrap diodes, reducing the need for external circuitry, as well as having under-voltage and short-circuit protection functions. These new 8-bit core BD66FM6746G / BD66FM6752G devices and 32-bit Arm® Cortex®-M0+ core HT32F65732G / HT32F65740G devices are suitable for use with 10~20 cell lithium batteries which see popular use in garden and power tools, 36V~72V pumps, fan products and many other application areas.
The 8-bit BD66FM6746G and BD66FM6752G MCUs include 4KW and 8KW of flash program memory respectively, 512B and 2KB of RAM Data Memory respectively and have an operating frequency of up to 20MHz.
The 32-bit HT32F65732G and HT32F65740G MCUs are designed for 1-shunt and 2-shunt FOC. These devices include 32KB and 64KB of flash memory respectively and 4KB and 8KB of SRAM respectively and have an operating frequency of up to 60MHz.
