Texas Instruments LMH13000 High-Speed Current Driver
Texas Instruments LMH13000 High-Speed Pulsed and Continuous Output Current Driver is a LiDAR laser driver that supports fast rise and fall times of <1ns for pulsed current-output applications. This voltage-controlled current source enables accurate current control, and using the VSET pin helps adjust load currents to compensate against variations with aging and temperature. The LMH13000 module supports continuous currents up to 1A and pulsed currents up to 5A, depending on frequency, heat dissipation, and duty cycle. The LMH13000 current driver from Texas Instruments is housed in a TI proprietary HotRod™ package that eliminates the internal bond wires that help achieve an ultra-low inductance in the high-current path, enabling designs to reach faster current rise and fall times. The device operates between 3V and 5.5V, with an ambient temperature range of -40°C to +125°C (+150°C maximum die temperature). An integrated thermal shutdown protects the die from excessive die temperature.
