Texas Instruments’ LMG1025-Q1 single-channel low-side driver for enhancement-mode GaN FET and logic-level MOSFET is for use in high-switching-frequency automotive applications.
Narrow pulse width capability, fast switching specification, and small pulse distortion combine to significantly enhance LiDAR, time-of-flight (ToF), and power converter performance.
This, combined with 300ns distortion, leads to longer-range and precise LiDAR/ToF systems. 2.9ns propagation delay significantly improves the control loop response time, and thus the overall performance of the power converters.
The 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 that the device is not damaged in overload or fault conditions.
The 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.
Mouser also offers the LMG1025-Q1EVM evaluation module, which demonstrates the switching performance of the LMG1025-Q1 single-channel low-side driver.
Applications for the driver include automotive LIDAR, driver monitoring, vehicle occupant detection sensors, and DC-DC converters.
