L6569AD Description

Short technical summary and product information.

The STMicroelectronics L6569AD is a high voltage half bridge driver featuring an integrated oscillator, suitable for driving external N-channel MOSFETs and IGBTs. This device operates with a high voltage rail up to 600V and incorporates BCD off-line technology.

 

Key electrical characteristics include a driver current capability of 170mA source and 270mA sink, a very low start-up current of 150 μA, and under-voltage lockout with hysteresis. The programmable oscillator frequency allows for flexible design, and the internal logic ensures a typical dead time of 1.25 μs to prevent cross-conduction.

 

Designed for surface mounting, the L6569AD comes in an 8-SOIC package. It operates within a supply voltage range of 10V to 16.6V and an ambient operating temperature range of -40°C to 125°C. The device also includes an internal bootstrap diode structure and a 15.6V Zener clamp on VS.
