... An integrated bootstrap section, eliminating the nor- mally required bootstrap diode and the zener clamp- ing on Vs, makes the L6574 well suited for low cost applications where few additional components are needed to build a high performance ballast. V ...

... Non Inverting Input of the operational amplifier. 8 EN1 Enable 1. This pin (active high), forces the device in a latched shutdown state (like in the under voltage conditions). There are two ways to resume normal operation: – the first is to reduce the supply voltage below the undervoltage threshold and then increase it again until the valid supply is recognised. – ...

... Supply Voltage. This pin, connected to the supply filter capacitor, is internally clamped (15.6V typical). 13 N.C. Non Connected. This pin set a distance between the pins related to the HV and those related to the LV side. 14 OUT High Side Driver Floating Reference. This pin must be connected close to the source of the high side power MOS or IGBT ...

... MOSFET. This function is achieved using a high voltage DMOS driver which is driven synchronously with the low side external power MOSFET. For a safe operation, current flow into the Vboot pin is inhibited, even though ZVS operation may not be ensured. Timing Section: To set the proper preheat time (tpre=kpre*Cpre) for the bulb, a capacitor is connected to the Cpre pin which is charged with a fixed current ...

... Short pulses (>200nsec) at the comparator inputs are rec- ognized. The EN1 input (active high) forces the L6574 in the shut down state (e.g. LVG low, HVG low, oscillator stopped) in the event of an undervoltage condition. Normal operating condition is resumed after a power- off power-on sequence or when EN2 input is high ...
