The MCP8048 Functional Safety-Compliant Three-Phase Brushless Motor Gate Driver System Basis Chips (SBCs) for brushless motor control are designed using advanced 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 enable duty-cycle operation 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 schematics) detection module and a window watchdog. The microcontroller controls the MCP8048 using an SPI interface. The MCP8048 is available in a 48-pin VQFN package and integrates three operational amplifiers and a physical LIN bus interface and the option to disable the LIN dominant timeout, which allows PWM operation.
