AEC-Q100 grade 1 qualified
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.
1.25-ns output pulse width enables more powerful,
eye-safe diode pulses. This, combined with 300-ns
distortion, leads to longer-range, precise LiDAR/ToF
systems. 2.9-ns 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.
1.25-ns typical minimum input pulse width
2.6-ns typical rising propagation delay
2.9-ns typical falling propagation delay
300-ps typical pulse distortion

2-mm x 2-mm QFN package
Inverting and non-inverting inputs
UVLO and over-temperature protection
Single 5-V supply voltage
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.
