Overview
Description
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.

RAA227063 unable to switch mosfets when bldc is connected
Hello I am trying to build a three phase inverter based on the RA227063. I am currently using a PCB that was designed based on the Renesas evaluation board for the same chip. During the initial testing, the board appears to work as expected. SPI communication works and all the ...

RAA227063 internal buck-boost compensation
First of all I'm sorry if this sounds like a silly question. I'm designing a 3ph inverter for a brushless dc motor using RAA227063. Neat little chip. I have some doubts with regard to the compensation network I have to apply to the buck-boost converter (buck only ...

RAA227063 Internal LDO Outputs Voltage Level
Hello, We have a RAA227063 custom board. If we do not ENABLE RAA227063; AUXVCC=~2.7V(sometimes 2.4V) and VCC=~5V. After enable RAA227063, AUXVCC goes up ~3.3V and VCC=5V. where VBUS=24V, load=27mA(read from power supply unit, Vbus=24V), VDRV=12V, EN=3.3V ...
