EPC21701

Overview

The EPC21701 is an integrated laser driver IC designed for Time-of-Flight (ToF) LiDAR systems. It combines an 80 V, 40 A GaN FET with a gate driver and 3.3 V logic-level inputs on a single chip. The device operates from a 5 V supply and supports laser drive currents up to 15 A. It enables pulse modulation at frequencies exceeding 50 MHz with pulse widths under 2 ns. Key timing specifications include voltage switching times of less than 1 ns and input-to-output delays of less than 3.6 ns.

Feature Summary

• Integrates high-voltage GaN power switch with control logic
• Supports ultra-short pulse generation for precise ranging
• Compatible with standard 3.3 V digital interfaces

Applications

• Time-of-Flight measurement modules
• Gesture recognition systems
• Driver monitoring and awareness systems
• Machine vision applications
• Industrial safety LiDAR sensors

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel configuration. Ensure the supplier provides original manufacturer documentation to validate authenticity. Confirm that the component meets the required automotive or industrial qualification standards if applicable to your design. Check for compatibility with the intended PCB footprint and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when designing compact ToF LiDAR systems requiring high peak current and fast switching speeds. It is suitable for applications using VCSEL lasers where space constraints limit discrete solution options. Consider its integration level to simplify board layout and reduce component count compared to separate driver and FET solutions.

Part Context

This part belongs to EPC's eToF™ series of laser drivers, specifically engineered for solid-state LiDAR. It leverages Gallium Nitride technology to achieve performance levels unattainable with silicon MOSFETs. The device addresses the need for high-frequency modulation in consumer electronics and automotive sensing applications.
