The LMH13000 is a voltage-controlled current source that enables accurate current control for driving lasers and other current control loads. The LMH13000 supports fast rise and fall times (< 1ns) for pulsed current-output applications without the need for an external FET. The LMH13000 can drive multiple laser types including: edge-emitting lasers (EEL), vertical-cavity surface-emitting lasers (VCSEL), and more. The VSET pin accurately adjusts the load current to compensate against variations for temperature and aging of the laser diode.
The LMH13000 delivers up to 1A-continuous or 5A-pulsed current depending on frequency, duty cycle, and heat dissipation. The high output impedance allows multiple LMH13000 to be paralleled easily. The LMH13000 comes in a TI proprietary HotRod™ package. This package eliminates the internal bond wires that help achieve a very low inductance in the high-current path, thereby enabling 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 inputs (EP and EN) enable control of the output current on-time, frequency, and duty cycle. The LMH13000 operates between 3V to 5.5V, with a specified ambient temperature range of –40°C to +125°C (maximum die temperature of 150°C).
