LD06AJSA/B is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant output current can be set up to 1.5A with an external resistor.
The LD06AJSA/B consists of high precision reference voltage, amplifier, current mirror, etc. The on-chip power transistor and current sense block greatly reduce the external component count, which makes the LD06AJSA/B ideal for LED driver.
When the CE pin is high, the input voltage is greater than 2.8V, and is larger than the LED forward voltage plus the required voltage drop, LD06AJSA/B functions normally to deliver constant current from the LED pin.
The LD06AJSA/B adopts the temperature regulation instead of temperature protection function, the temperature regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage drop.
When the LD06AJSA/B junction temperature reaches about 135 ° C, the internal temperature regulation block reduces the LED current so that the junction temperature will not rise any more.
This feature allows the users to maximize the use of the power handling capability of the chip, do not worry about the chip overheating and damage to the chip or external components.
The LD06AJSA/B also has the chip enable function, which can shutdown the whole chip to limit the current consumption within 1uA.
The LD06AJSA/B also adopts the over current protection block. When LED current approaches 1.9A(Typical), the over current protection block begins to function to prevent the LED current from increasing further.
