ICL7667CPA+

Gate Driver Overview

The ICL7667CPA+ is a dual inverting MOSFET gate driver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4.5 V to 17 V and delivers an output current of 10 mA per channel. The device features symmetric rise and fall times of 20 ns, ensuring balanced switching performance. It is housed in an 8-pin PDIP package designed for through-hole mounting. The component supports a wide operating temperature range from 0°C to +70°C and dissipates up to 200 mW of power.

Gate Driver Feature Summary

• Dual-channel configuration providing independent control signals for multiple MOSFETs
• Inverting logic interface that complements standard control signal polarities
• Symmetric 20 ns propagation delays for consistent high-frequency switching behavior

Gate Driver Applications

• Driving N-channel power MOSFETs in low-power switching circuits
• Interface stages in motor control systems requiring inverted drive signals
• General-purpose digital-to-analog buffer applications involving MOSFET loads

Gate Driver Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure the procurement source provides valid traceability records for the PDIP-8 package variant. Cross-reference the lot code with current production status notices to avoid obsolete inventory risks during integration.

Gate Driver Selection Notes

Select this component when a dual-channel inverting driver is required for through-hole PCB layouts. The 10 mA output capability suits moderate-speed applications where minimal drive strength is sufficient. Consider the 4.5 V minimum supply constraint when designing low-voltage power domains. Evaluate thermal dissipation requirements relative to the 200 mW power rating in enclosed environments.

Gate Driver Part Context

This part belongs to the ICL7667 series of dual MOSFET drivers, representing a legacy product line from Maxim Integrated now managed by Analog Devices. The series focuses on providing reliable inversion and buffering for power switching elements. The CPA+ suffix indicates a lead-free, RoHS-compliant version of the original commercial grade device, maintaining historical pin compatibility.
