ICL7667EPA Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The ICL7667EPA is a gate driver IC designed for half-bridge configurations with inverting input logic. It features independent dual-channel N-channel MOSFET driving capability and operates across a 4.5V to 17V supply voltage range. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. The ICL7667EPA+ serves as the direct active substitute, offering identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICL7667EPA is determined by strict equivalence across the following critical parameters:

• Dual independent N-channel MOSFET drivers with inverting input logic
• Supply voltage range of 4.5V to 17V
• Logic threshold levels (VIL = 0.8V, VIH = 2V)
• Switching performance with 20ns rise and fall times
• 8-DIP through-hole package (0.300", 7.62mm)
• Operating temperature range of 0°C to 150°C

The ICL7667EPA+ maintains complete electrical and mechanical compatibility with the original part while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ICL7667EPA+ is the direct equivalent substitute for the obsolete ICL7667EPA. Both devices share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional interchangeability in half-bridge gate driver applications.

The primary distinction between the two parts is product lifecycle status and regulatory compliance. The ICL7667EPA+ carries active product status from the manufacturer, ensuring continued availability and support. Additionally, the ICL7667EPA+ meets ROHS3 compliance requirements, whereas the original ICL7667EPA is non-compliant. For new designs and production applications requiring regulatory adherence, the ICL7667EPA+ is the appropriate selection.

Both devices maintain identical REACH unaffected status and MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the ICL7667EPA+ be used as a direct replacement for the ICL7667EPA?

A: Yes. The ICL7667EPA+ is electrically and mechanically identical to the ICL7667EPA. All electrical parameters, including supply voltage range, logic thresholds, switching times, and operating temperature, are equivalent. The 8-DIP through-hole package dimensions are identical, enabling direct substitution without circuit modifications.

Q: Why is the ICL7667EPA classified as obsolete?

A: The ICL7667EPA has reached end-of-life status with the manufacturer. The ICL7667EPA+ represents the active continuation of this product line with maintained specifications and improved compliance status.

Q: What is the difference in RoHS compliance between these parts?

A: The ICL7667EPA is RoHS non-compliant, while the ICL7667EPA+ meets ROHS3 compliance standards. For applications subject to RoHS regulations or customer requirements, the ICL7667EPA+ is the required selection.

Q: Are there any differences in packaging or handling requirements?

A: Both devices share identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. The ICL7667EPA+ is supplied in tube packaging, while the original part packaging specification is not detailed. Both maintain identical REACH unaffected status.

Q: What applications are these gate drivers suitable for?

A: These devices are designed for half-bridge gate driver applications requiring independent dual-channel N-channel MOSFET control with inverting input logic. The 4.5V to 17V supply range and 20ns switching times support power conversion and motor control topologies operating within these specifications.
