EPC expands eToF laser driver IC family of products

EPC has introduced a laser driver that integrates a 40V, 10 A FET with a gate driver and low-voltage differential signaling (LVDS) logic level input in a single chip for time-of-flight lidar systems used in robotics, drones, augmented reality, and gaming applications.

The EPC21603 is a laser driver that is controlled using LVDS logic and is capable of very high frequencies exceeding 100 MHz and super short pulses (< 2 ns) to modulate laser driving currents up to 10 A. It is a single-chip driver plus eGaN FET which uses EPC’s proprietary GaN IC technology in a chip-scale BGA form factor that measures only 1.5 mm x 1.0 mm. The LVDS logic control allows the eToF laser driver IC to be controlled from an FPGA for applications where noise immunity is critical, such as augmented reality.

Integrated devices in a single chip make it easier to design, easier to layout, easier to assemble, save space on the PCB, increase efficiency, and reduce cost. This family of products will, according to EPC, enable faster adoption and increased ubiquity of ToF solutions across a more comprehensive array of end-user applications.

The EPC9156 development board features the EPC21603 eToF laser driver IC and is primarily intended to drive laser diodes with short, high current pulses. Capabilities include minimum pulse widths of < 2 ns, 10 A peak currents, and bus voltage rating of 30 V.
