Robust 1200V control ICs reduce design cycle

International Rectifier's 1200V-rated IR2214 and IR22141 high voltage integrated circuits (HVICs) for industrial motor drive control can be safely used as a single-part solution in high voltage industrial systems for protection circuits as well as high- and low-side switching. Competing devices rated at lower voltages typically use several components and bulky optocouplers to accomplish the same switching and protection functions.
The new half-bridge gate driver ICs are designed specifically for 400VAC, three-phase ac induction motor drives using a 550V bus as well as brushless dc motors both from 10 to 20 horsepower. They simplify motor control design by integrating protection circuitry and eliminating the need for customized programming of protection algorithms.

Other benefits include a full range rail-to-rail output stage that allows up to 20V gate drive providing a larger safe operating area (SOA), and an undervoltage lockout with hysteresis that minimizes the effects of power supply ripple and transients for safe gate drive and prevents IGBT overheating.

IR2214SS and IR22141SS, $3.50 (10,000).
