3 / 10 page 3/10 L6574 ABSOLUTE MAXIMUM RATINGS (*) The device has an internal Clamping Zener between GND and the VCC pin, it must not be supplied by a Low Impedance Voltage Source. Note: ESD immunity for pins 14, 15 and 16 is guaranteed up to 900V (Human Body Model) 9 EN2 Enable 2. EN2 input (active high) restarts the start-up procedure (preheating and ignition sequence). This features is useful if the lamp does not turn-on after the first ignition sequence . 10 GND Ground. 11 LVG Low Side Driver Output. This pin must be connected to the low side power MOSFET gate of the half bridge. A resistor connected between this pin and the power MOS gate can be used to reduce the peak current. 12 VS 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. 15 HVG High Side Driver Output. This pin must be connected to the high side power MOSFET gate of the half bridge. A resistor connected between this pin and the power MOS gate can be used to reduce the peak current. 16 VBOOT Bootstrapped Supply Voltage. Between this pin and VS must be connected the bootstrap capac- itor. A patented integrated circuitry replaces the external bootstrap diode, by means of a high voltage DMOS, synchronously driven with the low side power MOSFET.
