ACPL-M49T
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 V_CM = 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.
