SNOSD74B MAY 2019REVISED JANUARY 2020  
LMG1025-Q1 Automotive Low Side GaN and MOSFET Driver  
For High Frequency and Narrow Pulse Applications  
1 Features  
3 Description  
The LMG1025-Q1 is a single channel low-side  
1
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  
Independent 7-A pull-up and 5-A pull-down  
current  
650-ps typical rise time (220-pF load)  
850-ps typical fall time (220-pF load)  
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.
