San Jose, Calif. Avago Technologies has delivered three high-temperature, high-speed digital optocouplers, which are said to be the first in the industry for use in industrial applications. These wide temperature optocouplers operate over a wide temperature range from -40° to 125°C making them suitable for use in applications that operate in harsh industrial environments.
The latest additions to Avago's optocoupler family include a 1 MBd single-channel digital optocoupler (ACPL-M43U), a 10 MBd logic gate optocoupler (ACPL-M61U), and an intelligent power module optocoupler that includes an aluminum gallium arsenide (AlGaAs) layer optically coupled to an integrated high-gain photo detector (ACPL-M46U). These high-speed digital optocouplers are low-power and high common mode transient rate (CMR) components that provide immunity to transient noises, EMI and ground loop eliminations. The ACPL-M43U, M46U and M61U optocouplers, housed in a 5-pin surface-mount package, are compliant to most industrial safety standards such as IEC/EN/DIN EN 60747-5-2, UL 1577 and CSA.
The difference between the ACPL-M43U and M46U is that the M46U offers excellent propagation delay difference that allows the circuit designer to reduce switching dead time to improve inverter efficiency, said Avago. These extended temperature IPM optocouplers are suitable for use in battery management systems, motor control, isolated IGBT/MOSFET gate drives, AC and brushless DC motors, and industrial inverters for power supplies.
The ACPL-M61U 10 MBd optocoupler targets industrial communications interface applications. Its optically-coupled gates, combined with a AlGaAs LED and integrated high-gain photo detector, are well-suited for use with most industrial communication interfaces (such as RS232, RS485, CANBus etc), high-temperature digital signal isolation, microcontroller interfaces, and digital isolation for A/D and D/A conversion.
Pricing: The ACPL-M43U, ACPL-M46U and ACPL-M61U optocouplers are priced at $1.50, $1.63 and $1.75, respectively, in quantities of 10,000 quantities.
Availability: Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
