Renesas Electronics RAA2270634GNP#MA0, BLDC Motor Driver IC

The Renesas Electronics 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. 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.
