The PM20225G-08 series is a dedicated motor driver chip utilising the ARM® Cortex®-M0 core, operating at a maximum frequency of 64MHz, with integrated 32Kbyte Flash and 4Kbyte SRAM.

The PM20225G-08 incorporates one 16-bit advanced timer, one 32-bit general-purpose timer, one 16-bit generalpurpose timer, and one 24-bit Hall sensor dedicated timer.

The integrated analog circuit includes: one 12-bit ADC (supporting 14 external analog input channels and 6 internal input channels), two programmable operational amplifiers (with PGA1 supporting dual-phase current polling amplify), two voltage comparators (incorporating BEMF neutral point real-time detection),one power-on/powerdown reset circuit (POR/PDR), one Programmable Voltage Detector/Brown-Out Reset circuit (PVD/BOR), one internal temperature sensor, one internal reference voltage (sampled via the on-chip ADC), and an internal analog power supply circuit delivering 2.4V/3.6V outputs.

All pins on the PM20225G-08, except power supply and ground, can function as GPIO, peripheral I/O, or external interrupt inputs.

The PM20225G-08 supports conventional Flash read/write protection.

The PM20225G-08 supports multiple communication interfaces: 2 serial UARTs, 1 high-speed SPI, and 1 I²C.

The PM20225G-08 further integrates a hardware division-square root unit (DVSQ) to enhance software processing capabilities and rapid response to external events.

The PM20225G-08 supports low-power Sleep and Stop modes, making it suitable for applications demanding high chip power efficiency.

Built-in 5V 50mA LDO and 12V LDO control circuits with output short circuit protection.

Built-in three-phase brushless gate driver, capable of operating at up to 50V, is designed to drive MOSFETs with a 6N structure.
