Half-Bridge FredFet

and Integrated Driver

Description

IR3101 is a gate driver IC integrated half bridge FredFET designed for sub 250W (heat-sink-less) motor drive

applications. The sleek and compact single-in-line package is optimized for electronic motor control in

appliance applications such as fans and compressors for refrigerators. The IR3101 offers an extremely

compact, high performance half-bridge inverter, in a single isolated package for a very simple design for two-

phase and three-phase motor drivers.

single package construction. Propagation delays for the high and low side power FredFETs are matched

thanks to the advance IC technology.

Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-

eters are absolute voltages referenced to COM. The thermal resistance and power dissipation are measured under

board mounted and still air conditions.

Note 1: under normal operational conditions: both power devices working, no heatsink
