HIP Bridge Driver Portfolio Expanded by Intersil

The HIP2120, HIP2121, HIP2122 and HIP2123 products provide more flexibility to control the half-bridge MOSFETs and to reduce the component count of the application circuit. Additionally, the integrated delay timer allows designers to adjust the dead-time between the two outputs via an external resistor, eliminating the shoot-through current that can occur in half-bridge and synchronous buck topologies. The new drivers are designed for telecom isolated half-bridge DC/DC converters, non-isolated DC/DC converters, motor drivers, Class-D amplifiers and a variety of other applications.
