Description:

The GD30DRE230x device integrates a 32-bitCortex®-M23 core MCU and a three-phase gatedriver. The device supports multiple applications,such as motors, electronic bikes, power tools, etc.The device provides up to 64 KB on-chip flashmemory and up to 8 KB SRAM memory. Anextensive range of enhanced I/O and peripheralsconnected to two APB buses. The devices offerone 12-bit ADC, a comparator, up to four general16-bit timers, a PWM advanced timer, as well as standard communication interfaces: SPI, I2C, USART,I2S. 

The driver of GD30DRE230x includes three half-bridgedrivers, each is capable to driving two NMOSFETs andsupports up to 1A source and 1.2A sink current capability.The drive currents will be adapted automatically to theoptimized current according to different power MOSFETused in the application. A proprietary slew rate control isimplemented to reduce the EMI of gate drive. Aregulated charge pump supporting 100% duty cycle isintegrated in the device to supply the gate drive currentand the internal LDOs.The device inserts fixed dead-time and uses automatichandshaking to prevent the high-side and low-sideMOSFET from shoot-through when switching.The GD30DRE230x device supports system dataprocessing, daily transaction processing, highperformance control calculation, driving MOSFET. It canbe used in a broad range of applications, such as 3-phase BLDC/PMSM motors, electronic bikes, powertools.
