The L6569 and L6569A are high‑voltage half‑bridge drivers with an integrated oscillator, designed to drive external N‑channel MOSFETs or IGBTs up to 600 V. They include internal bootstrap, programmable dead‑time, and very low start‑up current.
Key features include a supply voltage range of 10 V to 500 V, a typical oscillator frequency of 200 kHz, low‑side sink current of 270 mA, dV/dt immunity up to 50 V/ns, and a typical dead‑time of 1.25 µs.
| Supply Voltage (Vs) range | 10 V to 500 V |
|---|---|
| Oscillation Frequency | 200 kHz |

The device can operate with a floating supply voltage up to 500 V.
The nominal oscillator frequency is 200 kHz.
The driver provides a typical dead time of 1.25 µs.
Pins 6, 7 and 8 are protected up to 900 V (Human Body Model).
