ICL7667CPA

Gate Driver Overview

The ICL7667CPA is a dual power inverting MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 17V and features an inverting logic configuration with two independent drivers. The device provides typical rise and fall times of 20ns each, supporting efficient switching performance. Designed for surface-mount or through-hole integration depending on the variant, it functions reliably across an extended temperature range from 0°C to +150°C junction temperature. Packaged in an 8-pin DIP format, this component serves as a robust interface between low-voltage control logic and high-power N-channel MOSFETs.

Gate Driver Feature Summary

• Dual independent channel architecture for simultaneous control of multiple power switches
• Inverting signal configuration ensures logical complement output states relative to inputs
• Extended thermal capability supports operation up to 150°C junction temperature

Gate Driver Applications

• Driving N-channel MOSFETs in half-bridge converter topologies
• Isolated gate drive stages in DC-DC conversion circuits
• Motor control systems requiring complementary switch activation

Gate Driver Procurement Notes

Verify current availability status as distribution channels may list limited stock or obsolete status. Confirm package authenticity and RoHS compliance markings upon receipt. Cross-reference manufacturer part numbers with distributor listings to ensure exact match. Check for updated datasheets reflecting any design revisions or testing requirements specific to this batch.

Gate Driver Selection Notes

Select this component when dual isolated gate driving is required for N-channel MOSFETs. Ensure input logic levels align with the specified VIL and VIH thresholds. Verify that the operating voltage remains within the 4.5V to 17V range. Consider thermal management solutions if junction temperatures approach the maximum limit during continuous operation.
