The PM30225Q-0405 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 PM30225Q-0405 incorporates one 16-bit advanced timer, one 32-bit general-purpose timer, one 16-bit general-purpose 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 PM30225Q-0405, except power supply and ground, can function as GPIO, peripheral I/O, or external interrupt inputs.
The PM30225Q-0405 supports conventional Flash read/write protection.
The PM30225Q-0405 supports multiple communication interfaces: 2 serial UARTs and 1 I²C.
The PM30225Q-0405 further integrates a hardware division-square root unit (DVSQ) to enhance software processing capabilities and rapid response to external events.
The PM30225Q-0405 supports low-power Sleep and Stop modes, making it suitable for applications demanding high chip power efficiency.
The PM30225Q-0405 incorporates a three-phase brushless gate driver capable of operating up to 36V, designed to drive P+N structure MOSFETs.
It integrates three half-bridge P+N MOSFETs supporting low RDS(ON) values.
Operating within a temperature range of -40°C to +105°C and a supply voltage of 5V to 24V, the PM30225Q-0405 meets the requirements of most application environments.
