Wide Operating Temperature Automotive R2Coupler™

20-kBd Digital Optocoupler Configurable as Low

Power, Low Leakage Phototransistor

Data Sheet

Description

The ACPL-M49T is a single channel, high temperature, high

CMR, 20-kBd 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.
