Intersil expands HIP bridge-driver portfolio
Adds four new 2-A high-voltage half-bridge MOSFET drivers
Intersil announced the expansion of the industry leading HIP portfolio of MOSFET bridge drivers for power-supply and motor-drive applications. This family of 100-V, 2-A, high-frequency half-bridge drivers provides short rise and fall times, adjustable dead-time, and flexible control outputs. 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.
