Analog Simulation - MCP8048 and MCP8049

The MCP8048/MCP8049 are Functional Safety Compliant Three-Phase Brushless Motor Gate Driver System Basis Chips (SBC) for brushless motor control, designed using advanced Silicon on Insulator (SOI technology). In combination with a microcontroller and six discrete power MOSFETs, the SBC forms a brushless DC motor control unit. The Gate Driver Units (GDU) are controlled independently through six dedicated parallel inputs. Charge pumps for low and high-side gate drive allow duty cycle operations from 0% to 100%. In addition, the SBC provides 5V and 3.3V low dropout voltage regulators, current-sensing operational amplifiers, an integrated Back-EMF (BEMF in the Block Diagram) detection module and a window watchdog. The microcontroller controls the MCP8048/MCP8049 using a Serial Peripheral Interface (SPI).
