Want to post a buying lead? If you are not a member yet, please select the specific/related part number first and then fill the quantity and your contact details in the "Request for Quotation Form" on the left, and then click "Send RFQ".Your buying lead can then be posted, and the reliable suppliers will quote via our online message system or other channels soon.
The device is a high voltage half bridge driver with built in oscillator. The frequency of the oscillator can 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. 1.25s] to avoid crossconduction of the power devices.
Two version are available: L6569 and L6569A. They differ in the low voltage gate driver start up sequence.
