RN5C750
4ch RGB Laser Diode Driver for Display System, for Automotive Applications
The RN5C750 is a laser-diode driver designed to support four-channel RGB/RGGB displays for driving laser scanning systems. By connecting photo diodes (PD), this device is capable of automatically detecting a threshold current and a light emitting current of each channel of the laser-diode drivers (LD).
KEY BENEFITS
- 200Mdot/sec High Speed Sink Type 10-Bit Current DAC RGGB 4-Channel Configuration.
- Equipped with TIA/PGA for PD Light Receiving System and Automatic Setting Functions of Increase/ /Decrease Rate for LD Light Emitting Current and LD Threshold Current.
- QFN 56-Pins Wettable Frank Compatible.
- Provided Safe Pin Arrangement with Consideration for Shorting between Adjacent Pins.
