3-phase gate drive simplifies eBike design

The IR3230SPbF is a three-phase gate drive IC designed specifically to meet the needs of dc brushless motors in eBike inverters. The device offers input range from 6 to 60 V, enabling operation from 48-V battery systems, regeneration mode to recharge the battery, and the integration of protection features.

The IR3230SPbF gate driver integrates the sensor interface and 120° angle or 60° angle selection capability, which eliminates the need for a programmable logic array. An integrated charge pump enables the removal of three electrolytic capacitors required in a typical system. The IR3230SPbF is available in an SOIC28 package. ($0.95 ea/10,000 — available now.)
