The LMH13000 is a voltage-controlled current source that enables accurate current control coupled with LVDS input to support fast rise-and-fall times (< 1ns) for pulsed- and square-wave applications. The accurate output-current control helps adjust load currents on-the-fly to compensate against variations in temperature and aging, for loads like lasers, LEDs, optical amplifiers, and more. The LMH13000 supports up to a 1A continuous current or 5A pulsed current, depending on frequency, duty cycle, and heat dissipation.

The LMH13000 comes in a TI proprietary HotRod package. The HotRod package eliminates the internal bond wires that help achieve a very low inductance in the high-current path. This package enables the design to achieve faster current rise-and-fall times. The integrated thermal shutdown protects the die in case of excessive die temperature. The LVDS input enables control of the output current frequency and duty cycle, and helps achieve flexibility of pulse and square waveforms. The LMH13000 operates between 3V to 5.5V, with a –40°C to +125°C specified ambient temperature range.
