IR3230SPBF Gate Drive IC


IR's three-phase, IR3230SPbF, gate-drive IC simplifies eBike design


International Rectifier's IR3230SPbF is a highly integrated, three-phase, gate-drive IC designed specifically to meet the needs of eBike inverters. The new device offers an input range up to 60 V, enabling operation from 48 V 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, eliminating the need for a programmable logic array and simplifying the control scheme. An integrated charge pump enables the removal of three electrolytic capacitors required in a typical system.

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