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. Features and Specifications

  • 10-ns driver rise and fall times
  • Integrated delay timer is programmable with an external resistor
  • HIP2120 and HIP2121 have single PWM input and enable pin
  • HIP2122 and HIP2123 have independent high-side and low-side inputs
  • HIP2120 and HIP2122 have CMOS compatible inputs with hysteresis
  • HIP2121 and HIP2123 have 3.3-V TTL-compatible inputs
  • Wide supply voltage range of 8 to 14 V with supply under-voltage protection Pricing and Availability The HIP212x series is available now in compact 4- x 4-mm 10-pin or 9-pin DFN packages, with prices starting at $1.67 each in 1,000-unit quantities. Intersil Product deeplink
