The ACPL-M49T is a single channel, high temperature, high CMR, 20kBd digital optocoupler, configurable as a low power, low leakage phototransistor, specifically for use in the automotive applications. The SO-5 JEDEC registered (MO-155) package outline is surface mountable.
This digital optocoupler uses an insulating layer between the light emitting diode and an integrated photo detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector in a 5-pin configuration increase the speed up to a hundred times over that of a conventional phototransistor by reducing the base-collector capacitance. Common connections with the supply and output pins shorted in a 4-pin configuration delivers low power, low leakage performance as a phototransistor. The ACPL-M49T has an increased common mode transient immunity of 15kV/μs minimum at VCM = 1500V over extended temperature range.
Broadcom R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications.
