pSemi (formerly known as Peregrine Semiconductor) announced the availability of the PE29101 gallium nitride (GaN) field-effect transistor (FET) driver for solid-state light detection and ranging (lidar) systems. The PE29101 boasts the industry’s fastest rise times and a low minimum pulse width. In solid-state lidar systems, faster switching translates into improved resolution and accuracy in the lidar image.
The PE29101 is a half-bridge FET driver that controls the gates of GaN transistors. The driver outputs are capable of providing switching transition speeds in the sub-nanosecond range for switching applications up to 40 MHz. The PE29101 has a rise/ fall time of 1 ns with 100 pF load and a minimum output pulse width of 2 ns. It operates from 4 V to 6,5 V and can support a high-side floating supply voltage of 80 V. The PE29101 has an output source current of 2 A and an output sink current of 4 A.
