• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

A basic core set of components are
included in the HM169-00. This
enables a user to choose values for a
custom application. It includes a
BT139X-600E triac (although this is
not very suitable for designs
controlling powers below 600 W)
The HM169-00 also includes the rfi
suppression components which are
generally needed for inductive loads.
This enables an HM169-00 to quickly
be made up to satisfy any specific
need without worrying about finding
these less easily obtained parts.
However, for larger quantities, these
can usually be omitted for resistive
load applications, and it may be
possible to use smaller capacitor

Application examples are described
briefly in this data sheet, with each
model having its own supplementary
data sheet giving full details of which
additional components are needed,
as well as in one or two cases where
existing parts in the OM169-00 need
to be replaced or supplemented.

This section describes the circuit
design approach used in application
of the OM1682A precision control IC.
In the HM169 there are many options
to satisfy different application needs,

11.1
The HM169 circuits using the
OM1682A have been designed in
Australia, where the normal supply
voltage is 230 Volts. However the
OM1682A is interfaced to the mains
supply by a number of high voltage
resistors which can be selected to suit
the design supply voltage range.
The considerations involved in
choosing the power supply and triac
drive components is discussed in
detail in the application note AN001,
‘Power supply circuits for OM1682A
triac controller IC applications’. Also
