L6569 L6569A HIGH VOLTAGE HALF BRIDGE DRIVER WITH OSCILLATOR s HIGH VOLTAGE RAIL UP TO 600V s BCD OFF LINE TECHNOLOGY s INTERNAL BOOTSTRAP DIODE STRUCTURE s 15.6V ZENER CLAMP ON VS s DRIVER CURRENT CAPABILITY: - SINK CURRENT = 270mA - SOURCE CURRENT = 170mA s VERY LOW START UP CURRENT: 150µA s UNDER VOLTAGE LOCKOUT WITH HYSTERESIS s PROGRAMMABLE OSCILLATOR FREQUENCY s DEAD TIME 1.25µs s dV/dt IMMUNITY UP TO ±50V/ns s ESD PROTECTION DESCRIPTION The device is a high voltage half bridge driver with built in oscillator. The frequency of the oscillator can BLOCK DIAGRAM Minidip SO8 ORDERING NUMBERS: L6569 L6569D L6569A L6569AD be programmed using external resistor and capacitor. The internal circuitry of the device allows it to be driven also by external logic signal. The output drivers are designed to drive external nchannel power MOSFET and IGBT. The internal logic assures a dead time [typ. 1.25µs] to avoid crossconduction of the power devices. Two version are available: L656...
