Description
The HCPL-M454 is similar to
Agilent’s other high speed
transistor output optocouplers,
but with shorter propagation
delays and higher CTR. The
HCPL-M454 also has a
guaranteed propagation delay
difference (t
PLH
- t
PHL
). These
features make the HCPL-M454
an excellent solution to IPM
inverter dead time and other
switching problems.
The HCPL-M454 CTR, propaga-
tion delays, and CMR are
specified both for TTL load and
drive conditions and for IPM
(Intelligent Power Module) load
and drive conditions. Specifica-
tions 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 photon 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 photo-
transistor coupler by reducing the
base-collector capacitance.
