Three-Phase IR3230SPbF Gate Drive IC Simplifies eBike Design

Mon, 12/17/2012 - 7:24am


International Rectifier introduced the IR3230SPbF three-phase gate drive IC for eBike inverters providing efficient electric mobility.

The IR3230SPbF is a highly integrated three-phase gate drive IC designed specifically to meet the needs of eBike inverters. The new device offers input range up to 60V, enabling operation from 48V battery systems, regeneration mode to recharge the battery, and the integration of many protection features to reduce component count and improve system reliability. 

The IR3230SPbF integrates the sensor interface and 120°/60° selection capability which eliminates the need for a programmable logic array, and simplifies the control scheme while an integrated charge pump enables the removal of three electrolytic capacitors required in a typical system. 

“The IR3230SPbF is designed specifically for eBike applications, integrating all necessary functions and protection features to offer a more robust and reliable solution compared to discrete solutions,” said David Jacquinod, Product Marketing Manager, IR’s Automotive Products Business Unit.

The IR3230SPbF is available in an SOIC28 package featuring an environmentally friendly, lead-free and RoHS compliant bill of materials.
