Brown-out protection
The DC pin senses the voltage on the DC bus by means of an external resistor divider and an internal
comparator with hysterisis. When power is first supplied to the IC at system startup, 3 conditions are required
before oscillation is initiated: 1.) the voltage on the VCC pin must exceed the rising undervoltage lockout
threshold (VCCUV+), 2.) the voltage at the VDC pin must exceed VDC+, 3.) the voltage at the SD/EOL pin
must be below 3 V. If a low DC bus condition occurs during normal operation, or if power to the ballast is
shut off, the DC bus will collapse prior to the VCC of the chip (assuming the VCC is derived from a charge
pump off of the output of the half-bridge). In this case, the voltage on the VDC pin will drop below the VDC-
threshold and shut the oscillator off, thereby protecting the power transistors from potentially hazardous hard
switching. Approximately 2 V of hysterisis has been designed into the internal comparator sensing the VDC
pin, in order to account for variations in the DC bus voltage under varying load conditions. When the DC bus
recovers, the chip restarts from the beginning of the control sequence, as shown in timing diagram Figure 8
below.
