Optocouplers tackle harsher industrial environments

The ACPL-M43U, ACPL-M46U and ACPL-M61U optocouplers from Avago Technologies are able to operate at temperatures up to 125°C for tough industral applications.

The new devices allow equipment designers greater freedom when implementing isolation, enabling improved performance and signal integrity.

The ACPL-M43U and ACPLM46U support decoupling Intelligent Power Modules (IPM) in industrial motor-control systems. The ACPL-M43U has very high Common-Mode Rejection (CMR) of at least 30kV/µs for enhanced immunity to transient noise. The ACPL-M46U is optimised for close propagation-delay matching between devices to minimise dead-time in inverters and motor controls, leading to improved efficiency.

The ACPL-M61U supports data rates up to 10Mbit/s, enabling high-speed isolation for CANBus and MCU interfaces as well as ADCs and DACs. All devices feature internal shielding and an SO-5 package outline, which has 75% smaller footprint than the standard dual-inline package typically used for industrial optoisolators.

 

FEATURES International safety approvals: UL1577, CSA, IEC/EN60747-5-2 Tracking resistance meets DIN IEC 112/VDE 0303 part 1 Isolation group IIIa ≤5mm creepage and clearance 0.08mm minimum internal plastic gap

APPLICATIONS Industrial motor drives Inverters Isolated IGBT/MOSFET gate drives High-speed communications interfaces
