The internal circuitry of the device allows it to be DEAD TIME 1.25s driven also by external logic signal. n dV/dt IMMUNITY UP TO 50V/ns The output drivers are designed to drive external n- n ESD PROTECTION channel power MOSFET and IGBT. The internal log- s to avoid cross- ic assures a dead time typ. 1.25 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.
