AP1050AEN数据手册AKM中文资料规格书

描述 Description

The AP1050 is a pre-driver for a 3-phase brushless motor with built-in power supplies, which operates motor drive voltage in range of 8V to 36V. It incorporates a step-down DC-DC converter and LDOs to generate the power supply that the motor drive system requires. The bootstrap circuit is embedded and it enables to use N type MOSFET for both low side and high side.
