Ultra High CMR, Small Outline, 5 Lead, High Speed Optocoupler

Currently Viewing:

The Broadcom HCPL-M454 is a power module interface optocouplers.It is similar to Broadcom's  other high speed transistor output optocouplers, but with shorter propagation delays and higher CTR. It also has a guaranteed propagation delay difference (tPLH-tPHL). These features make the HCPCL-M454 an excellent solution to IPM inverter dead time and other switching problems.

Its 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 applications.

This diode-transistor optocoupler uses an insulating layer between the light emitting diode and an integrated photon detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increases the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base-collector capacitance.
