ICL7667EBA+

Gate Driver Overview

The ICL7667EBA+ 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 signal control. Designed for surface-mount applications, it utilizes an 8-SOIC package with a width of 3.90 mm. The component functions reliably across an operating temperature range from 0°C to +70°C, consuming 7 mA of quiescent current with a power dissipation rating of 200 mW.

Gate Driver Feature Summary

• Dual-channel architecture providing independent inverting drive signals for high-side and low-side MOSFET configurations.
• Symmetric propagation characteristics with matched rise and fall times to minimize switching distortion.
• Compact surface-mount packaging designed for efficient PCB layout in space-constrained power management circuits.

Gate Driver Applications

• DC-DC converter bridge driver stages
• Motor control interface circuits
• Inverter gate drive systems

Gate Driver Procurement Notes

Verify the specific suffix 'EBA+' against the official datasheet to confirm the SOIC-8 package and commercial temperature grade. Ensure the supplier provides traceability documentation matching Analog Devices or Maxim Integrated manufacturing records. Cross-reference the part number with authorized distributor lists to avoid counterfeit components, as availability may be restricted or subject to allocation.

Gate Driver Selection Notes

Select this component when designing circuits requiring dual inverting outputs for complementary MOSFET switching. The 10 mA drive capability suits standard power MOSFETs rather than high-capacitance loads. Verify that the system supply voltage remains within the 4.5 V to 17 V window. Consider the 0°C to +70°C operating range to ensure compatibility with the intended environmental conditions without requiring industrial-grade variants.

Gate Driver Part Context

This device belongs to the ICL7667C series of dual power MOSFET drivers. It serves as a specialized interface between logic-level control signals and power switches. The inverting configuration simplifies half-bridge driving topologies by eliminating the need for external phase-inversion logic. It is categorized under PMIC gate drivers within the broader power management integrated circuit portfolio.

Gate Driver Replacement Considerations

The ICL7667EBA-T is the tape-and-reel variant of this component, offering identical electrical performance and pinout. Substitution requires verification of the packaging format change only. Other family members like the ICL7667CBA+ share functional similarities but differ in packaging or temperature ratings.
