ICL7667EPA+

Gate Driver Overview

The ICL7667EPA+ is a dual inverting MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 17 V and delivers an output current of 10 mA. The device features symmetric rise and fall times of 20 ns, ensuring precise switching control. It supports a maximum power dissipation of 200 mW and functions reliably across an operating temperature range of 0°C to +70°C. Packaged in an 8-pin SOIC surface-mount format, it serves as a dedicated interface for driving N-channel MOSFETs in power management applications.

Gate Driver Feature Summary

• Dual-channel configuration providing independent inverting drive signals for two outputs
• Symmetric 20 ns rise and fall times for consistent switching performance
• Wide supply voltage compatibility supporting operation from 4.5 V to 17 V

Gate Driver Applications

• Driving dual N-channel MOSFETs in half-bridge configurations
• General-purpose low-power gate driving for power conversion circuits
• Interface logic between microcontrollers and power switches

Gate Driver Procurement Notes

Verify the specific suffix 'CBA' against the requested 'EPA' designation, as package types differ significantly between SOIC and PDIP formats. Confirm that the commercial temperature range (0°C to +70°C) aligns with system requirements, as industrial variants may exist. Ensure the inverting logic function matches the control signal polarity needed for the target MOSFET application.

Gate Driver Selection Notes

Select this component when a compact surface-mount solution is required for dual MOSFET control. The 10 mA output current is suitable for small-to-medium sized MOSFETs with moderate gate charge requirements. Consider the inverting nature of the driver when designing the control logic interface. Verify that the 200 mW power dissipation limit accommodates the thermal conditions of the final assembly.

Gate Driver Part Context

This part belongs to the ICL7667 series of dual MOSFET drivers, originally developed by Maxim Integrated before its acquisition by Analog Devices. The series provides a cost-effective solution for driving power switches in battery-powered and portable equipment. The 'EPA+' suffix indicates a lead-free, RoHS-compliant version of the original ICL7667 device, maintaining pinout compatibility with legacy designs while meeting modern environmental standards.
