Suggested RG(bI) is 15 kΩ.
11.7 Application schematics
The following schematics show possible implementations of TOPTriac. Gate trigger
current is from a 5 V minimum logic supply. It is possible to trigger from a 3.3 V
microcontroller by using a transistor level shifter to a higher voltage gate drive power
supply, which may be 5 V minimum or the 12 V supply that may already be available for
other loads such as lighting, indication and sounders.
For
DC triggering, reset is achieved by removing the gate drive at any time and
reapplying it after TOPTriac temperature has dropped below Ttrip.
For
pulse triggering, reset is achieved by removing and reapplying the gate bleed
current IG(bI) after TOPTriac temperature has dropped below Ttrip.
IG(bI) is set by RG(bI). It is best derived directly from the low voltage microcontroller supply
(up to 5V max) and will most likely be direct drive from the microcontroller output.
In all of the following circuits, gate trigger and gate bleed current are applied by logic zero
drive from the microcontroller.
