3 Description

The LMG1025-Q1 is a single channel low-side

enhancement-mode GaN FET and logic-level

MOSFET driver for high switching frequency

automotive applications. Narrow pulse width

capability, fast switching specification, and small

pulse distortion combine to significantly enhance

LiDAR, ToF, and Power Converter performance.

1.25ns output pulse width enables more powerful,

eye-safe diode pulses. This, combined with 300ns

distortion, leads to longer-range, precise LiDAR/ToF

systems. 2.9ns propagation delay significantly

improves the control loop response time and thus

overall performance of the power converters. Split

output allows the drive strength and timing to be

independently adjusted through external resistors

between OUTH, OUTL, and the FET gate.

The driver features undervoltage lockout (UVLO)

and over-temperature protection (OTP) to ensure the

device is not damaged in overload or fault conditions.

LMG1025-Q1 is available in a compact, leadless,

AEC-Q100 automotive qualified package to meet the

size and gate loop inductance requirements of high

switching frequency automotive applications.
