ACPL-M50L-500E Description

The ACPL-M50L-500E is an integrated circuit optocoupler that offers great performance and is designed for various applications. Some examples of these applications include power supplies, motor control systems, and communications equipment. Its function as an optocoupler allows it to maintain electrical isolation between the input and the output, providing both safety and dependability.

This article will present an in-depth reference to the ACPL-M50L-500E, detailing its most important characteristics and the benefits and applications for which it can be used. This article’s primary focus will be on its technical specs, performance characteristics, and suggested applications to provide you with the information you need to decide whether or not to include this optocoupler in your subsequent design endeavor.

BroadcomACPL-M50L ®’s, ACPL-054L (dual-channel in SO-8 size), ACPL-W50L (single-channel in stretched SO-6 footprint), and ACPL-K54L are all 1-MBd digital optocouplers that consume very little power and have very low input currents (dual-channel in stretched SO-8 footprint). These digital optocouplers have an insulating layer between the LED and the inbuilt photon detector. The function of this layer is to insulate the input and the output from any electrical interference.

One must use a photo-transistor coupler to obtain up to one hundred times faster than a regular photo-transistor coupler with independent connections for the photodiode bias and the output transistor collector. A lesser base-collector capacitance permits this. Throughout a temperature range of -40 degrees Celsius to +105 degrees Celsius, the ACPL-M50L/054L maintains a common mode transient immunity of at least 15 kilovolts per second when measured at a voltage of 1500 volts. The normal current transfer ratio (CTR) for an ACPL-M50L with an input current of 3 milliamperes is 140%, while the CTR for an ACPL-054L/W50L/K54L is typically 130%. This digital optocoupler can be used for wide-bandwidth analog operation as well as TTL/CMOS and LSTTL.
