ICL7667CPAZ

Gate Driver Overview

The ICL7667CPAZ is a dual monolithic high-speed gate driver designed to convert TTL level signals into high-current outputs at voltages up to 15V. It features a supply voltage range of 4.5V to 15V and operates within a temperature range of 0°C to 70°C. The device provides independent half-bridge configuration with two channels for N-channel MOSFETs. Input logic thresholds are defined by VIL at 0.8V and VIH at 2V. Typical rise and fall times are 20ns in an 8-SOIC package.

Gate Driver Feature Summary

• Converts low-level logic signals into high-current outputs suitable for driving power MOSFETs
• Provides fast switching speeds with minimal propagation delays for high-frequency applications
• Ensures direct interface compatibility with common pulse-width modulation control ICs

Gate Driver Applications

• Switching power supplies
• DC/DC converters
• Motor controllers

Gate Driver Procurement Notes

Verify the specific suffix designation, as variations such as CBAZA or CPA may indicate different packaging formats like tape-and-reel versus tube. Confirm that the component status aligns with current availability requirements, noting that some variants are marked as obsolete. Ensure the selected part matches the required thermal and electrical specifications for the target environment.

Gate Driver Selection Notes

Select this component when a dual channel driver is needed for N-channel MOSFETs with TTL-compatible inputs. The wide supply voltage range supports various logic levels. Consider the 8-SOIC package constraints for PCB layout. Verify that the peak output current capabilities meet the gate charge requirements of the intended power devices.

Gate Driver Part Context

This device belongs to the ICL7667 series of dual power MOSFET drivers. It serves as a pin-compatible replacement for older models like the DS0026 and DS0056. The series is characterized by its ability to drive large capacitive loads efficiently. Renesas Electronics Corporation manufactures this component under license from original design predecessors.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include ICL7667CPA and ICL7667CBAZ. These variants share identical functional characteristics but may differ in packaging type. Verify pinout compatibility before substitution.
