L6569A

Overview

The L6569A is a high-voltage half-bridge gate driver manufactured by STMicroelectronics. It operates within a supply voltage range of 10 V to 16.6 V and supports a maximum output voltage of 618 V. The device features two drivers with two outputs, designed for surface-mount or through-hole installation in SOIC-8 or PDIP-8 packages respectively. It functions at frequencies up to 0.2 MHz and maintains an operating temperature range from -40 °C to +125 °C. The component draws a working supply current of 25 mA and utilizes silicon technology.

Feature Summary

• Provides high-voltage half-bridge driving capability with synchronous high-side and low-side correlation.
• Integrates dual independent drivers for precise control of power switching elements.
• Designed for robust operation across extended industrial temperature ranges.

Applications

• High-voltage power management integrated circuits
• Industrial motor control systems
• Power supply unit designs requiring half-bridge topologies

Procurement Notes

Verify the specific package variant (SOIC-8 or PDIP-8) required for your design, as availability may vary between surface-mount and through-hole versions. Confirm RoHS compliance status and lead times directly with authorized distributors, as production cycles can extend significantly. Ensure that the selected revision matches the exact ordering suffix to guarantee correct electrical characteristics and pinout compatibility.

Selection Notes

Select this component when a dedicated high-voltage half-bridge driver is needed for applications exceeding standard logic-level voltages. Consider the 618 V output capability and 0.2 MHz frequency limit against system requirements. Evaluate thermal performance within the specified -40 °C to +125 °C range. Compare against alternative STMicroelectronics gate drivers if different packaging or drive strength is preferred.

Part Context

The L6569A belongs to the L6569 series of high-voltage half-bridge drivers from STMicroelectronics. This family includes variants such as the L6569D and L6569AD, which share similar functional architectures but differ in packaging and minor electrical specifications. The series is categorized under PMIC - Power Management ICs, specifically within the Gate Drivers subcategory, targeting efficient power conversion solutions.

Replacement Considerations

The L6569AD and L6569D are documented related parts within the same product family. Verify pinout compatibility and package differences before substitution. No other public substitute part numbers are confirmed in the provided documentation.
