ICL7667CBA-T

Gate Driver Overview

The ICL7667CBA-T is a dual monolithic high-speed gate driver designed to convert low-level control signals into high-current outputs for power MOSFETs. It operates within a supply voltage range of 4.5V to 15V and features an inverting input configuration compatible with TTL and CMOS logic levels. The device provides independent channels with peak output currents capable of rapidly charging and discharging gate capacitance, achieving typical rise and fall times of 20ns. Packaged in an 8-SOIC surface-mount format, it supports commercial operating temperatures from 0°C to 70°C.

• High-speed switching performance minimizes propagation delays during transitions
• TTL and CMOS input compatibility allows seamless integration with common digital control ICs

Gate Driver Applications

• Switching power supplies requiring efficient gate drive mechanisms
• DC/DC converters utilizing high-frequency switched mode topologies
• Motor controller circuits driving N-channel power MOSFETs

Gate Driver Procurement Notes

Verify component authenticity through authorized Renesas Electronics Corporation distributors or certified partners. Confirm the specific suffix matches the required package type and lead-free status. Check current lifecycle status as this series may be subject to discontinuation notices. Ensure storage conditions comply with moisture sensitivity level requirements prior to assembly.

Gate Driver Selection Notes

Select this component when designing circuits that require fast switching speeds and high current drive capability for N-channel MOSFETs. Consider the 8-SOIC package constraints for PCB layout and thermal management. Evaluate the 4.5V to 15V supply range against your system's available power rails. Verify that the inverting logic aligns with your PWM controller's output polarity before finalizing the design.
