RAA227063
4.5V to 60V 3-Phase Smart Gate Driver The RAA227063 is a smart gate driver IC for 3-phase
Brushless DC (BLDC) motor applications. It
integrates three half-bridge smart gate drivers that are
capable of driving up to three N-channel MOSFET
bridges and supports bridge voltages from 4.5V to
60V. Each gate driver supports up to 1A source and
2A sink peak drive current with programmable drive
strength control. Adjustable and adaptive dead-times
are implemented to ensure robustness and flexibility.
The active gate holding mechanism prevents a Miller
effect-induced cross-conduction and further
enhances robustness.
The device integrates power supplies that power
internal analog and logic circuitry, high-side and
low-side drivers, and a dedicated supply for powering
external microcontrollers. The device also features a
low-power Sleep mode that consumes only 20µA to
maximize battery life in portable applications.
The driver control inputs can be configured to either
3-phase LI/HI or 3-phase PWM modes. Three
accurate differential amplifiers with adjustable gain …
