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