Working Principle of LTM8005EY#PBF

The LTM8005EY#PBF is a multifunctional, highly integrated current source IC that can drive up to 4 independent LEDs with high accuracy. It is a self-contained, low-power device that consumes little current, making it an ideal solution for portable applications.

The device consists of four very precise current sources, each of which can drive a single LED. The output currents of each source are individually adjustable and are set by a single external resistor. This external resistor also sets the device’s operating mode, allowing it to achieve constant output current regulation and/or pulse width modulation.

The device also includes a number of protection features. It has an over-temperature protection (OTP) circuit that monitors the die temperature and shuts down the device if the temperature exceeds a certain limit. It also includes an over-current protection (OCP) circuit that monitors the output currents and shuts down the device if the output currents exceed a certain limit. The device is designed to be very robust, providing enhanced ESD protection.

Conclusion

The LTM8005EY#PBF is an advanced multichannel current source for driving multiple LEDs. It is designed to drive up to 4 independent LEDs while providing greater output accuracy, greater temperature stability, enhanced ESD protection and better over-temperature and over-current protection. The device is ideal for high current lighting applications such as automotive lighting, landscape lighting, medical lighting and general illumination.
