High CMR High Speed Optocoupler

Currently Viewing:

The ACPL-W454/P454 is similar to Broadcom other high speed transistor output optocouplers, but with shorter propagation delays and higher CTR. The ACPL-W454/P454 also has a guaranteed propagation delay difference (tPLH - tPHL). These features make the ACPL-W454/P454 an excellent solution to Intelligent Power Module ( IPM ) inverter dead time and other switching problems.

The ACPL-W454/P454 CTR, propagation delays, and CMR
are specified both for TTL load and drive conditions and
for IPM (Intelligent Power Module) load and drive
conditions. Specifications and typical performance plots
for both TTL and IPM conditions are provided for ease
of application.

This diode-transistor 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 increase
the speed up to a hundred times over that of a
conventional phototransistor coupler by reducing the
base-collector capacitance.
