Recovery from such a fault condition is accomplished
by cycling either the SD lead or the V
CC
lead. When
a lamp is removed, the SD lead goes high, the fault
latch is reset, and the chip is held off in an unlatched
state. Lamp replacement causes the SD lead to go
low again, reinitiating the startup sequence. The fault
latch can also be reset by the undervoltage lockout
signal, if V
CC
falls below the lower undervoltage
threshold.
Bootstrap Supply Considerations
Power is normally supplied to the high-side circuitry
by means of a simple charge pump from V
CC
, as
shown in Figure 19.
