L6569 is a high voltage half bridge driver with built-in oscillator from STMicroelectronics, with a maximum operating voltage of 600V, internal zener clamp between VS and VS, low start-up current of 150µA, programmable oscillator frequency, dead time of 1.25µs, dV/dt immunity up to ±50V/ns, ESD protection.
The L6569 and L6569A are high voltage half bridge drivers with an integrated oscillator, designed to drive external n-channel power MOSFETs and IGBTs. The device features a high voltage rail up to 600V and includes an internal bootstrap diode structure to charge the bootstrap capacitor, eliminating the need for an external diode in some applications. Two versions are available, differing in their low voltage gate driver startup sequence.
