Robust IGBT claims best-in-class CMTI
Designed to improve electric motor energy efficiency in industrial motor control, the ADuM4135 is an isolated IGBT gate driver from Analog Devices. It incorporates iCoupler digital isolator technology and galvanic isolation in a single package. It has, according to the company, the industry’s best combination of CMTI (Common-Mode Transient Immunity) at 100kV/µs and propagation delay of 50ns (typical).
The gate driver allows customers to comply with IE3 and IE4 motor efficiency standards, which are increasing required as higher-frequency switching technologies are used for both motor control and grid-inverters. Safety features include integrated Miller clamping and desaturation detection.
The low propagation delay and skew (15ns typical) can minimise dead time between low-side/high-side switching, minimising losses. The CMTI performance and low propagation delay also support SiC and GaN technologies which use higher switching frequencies in systems with increased transients. Peak drive output is 4A and resistance is up to 1Ω.
The driver is available in a 16-lead, wide-body SOIC package and provides 8mm creepage and clearance.
