Optocoupler is optimised for motor
control
A new optocoupler is optimised for reliability and performance in driving the intelligent power modules and IGBTs used for motor control in heavy industrial equipment.
Avago Technologies has introduced a new optocoupler optimised for reliability and performance in driving the intelligent power modules (IPMs) and integrated-gate bipolar transistors (IGBTs) used for motor control in heavy industrial equipment Avago's ACPL-4800 optocoupler meets the most stringent IPM performance specifications and is the first in the industry to offer common-mode rejection (CMR) of 30kV/us at 1.0kV

Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The ACPL-4800 features 50mA output current capability at up to 5Mbaud and guaranteed performance over the -40 to +100C temperature range.
The optocoupler is an excellent solution for improving the efficiency of inverter and motor drives through reduced switching dead time.
"The ACPL-4800 raises the bar for CMR performance to a high level of 30kV/us coupled with low power consumption", said Kheng-Jam Lee, Worldwide Marketing Manager for Isolation Products in Avago Technologies' Optical Communication Solutions Division.
"We'll continue to develop the industry's highest performance products to meet the needs of our industrial customers".
The ACPL-4800's totempole output with positive input-output logic means that no pull-up resistors or other additional circuitry is needed when connected to a positive-input IPM.
The optocoupler's combination of wide 5 to 20V operating voltage range, 350ns propagation delay and 250ns pulsewidth distortion with high common-mode transient immunity helps to ensure data integrity, even when equipment is operating in the electrically noisy environments common in manufacturing facilities.
Approval in accordance with the following safety standards is pending: UL 1557, CSA File CA88324 (Notice 5), and IEC/EN/DIN EN 60747-5-2.
The ACPL-4800 is fabricated using Avago Technologies' new bipolar-CMOS-DMOS (BCD II) process, resulting in a smaller, faster integrated circuit compared with conventional optocoupler ICs using a bipolar process.
The Avago ACPL-4800 is available in the following packages: gullwing surface-mount 8-pin DIP, lead-free 8-pin through-hole DIP, and lead-free gullwing surface-mount.
The ACPL-4800 is available now through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
