Shutdown and Low Power
With shutdown there are some unique power conditions. With the shutdown line low and the lamp ignited, the
PIC16F628 derives its power from the charge pump of the IR21592. The charge pump provides enough current
for the microcontroller to run at its internal frequency of
4MHz during normal operation. When the shutdown
line is asserted the IR21592 is disabled, and the charge
pump is no longer functioning. Current is drawn directly
from the high voltage DC line through a high value re-
sistor. The micro controller is put to sleep during this
time to minimize current draw and power dissipation.
To receive data, which requires significant current, the
PIC16F628 wakes up and starts the charge pump of
the IR21592 long enough to process the command, typi-
cally less than 25ms, but not long enough to ignite the
lamp (see waveforms in Figure 9). Doing this unique
management minimizes power dissipation during shut-
down.
