ICL7667EPA

Gate Driver Overview

The ICL7667EPA is a dual power 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. The device provides two independent channels with peak output currents of 10mA. Typical rise and fall times are 20ns each. It is housed in an 8-PDIP package and supports through-hole mounting. The component is designed for driving N-channel MOSFETs and functions reliably across a junction temperature range of 0°C to 150°C.

Gate Driver Feature Summary

• Dual-channel architecture for independent control of N-channel MOSFETs
• Inverting input logic configuration for signal phase inversion
• High thermal stability supporting extended junction temperatures up to 150°C

Gate Driver Applications

• Power management circuits requiring isolated or inverted gate drive signals
• Motor control systems utilizing N-channel MOSFET switching
• DC-DC converter topologies needing dual gate driver functionality

Gate Driver Procurement Notes

Verify the specific suffix 'EPA' corresponds to the 8-pin PDIP package variant when sourcing. Confirm RoHS compliance status as older manufacturing runs may differ from current specifications. Check for obsolescence notices from Analog Devices, as this component series has faced discontinuation trends. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Gate Driver Selection Notes

Select this component when dual inverting drivers for N-channel MOSFETs are required in through-hole designs. The 10mA output current suits moderate-speed applications where 20ns transition times are acceptable. Consider the wide operating temperature range for industrial environments. Verify that the 4.5V minimum supply voltage aligns with the system's available power rails before finalizing the design.

Gate Driver Part Context

The ICL7667 belongs to the Maxim Integrated dual MOSFET driver family, designed for efficient switching control. It serves as a legacy component often found in established industrial and consumer electronics designs. The EPA designation specifically identifies the plastic dual in-line package version, distinguishing it from surface-mount SOIC variants like the CBA series within the same functional lineup.
