BD18377EFV-ME2

The BD18377EFV-ME2 is a serial input controlled constant-current LED Driver with 10V output rating. 6-bit current calibration is available for each output while a global PWM performs dimming on all outputs simultaneously. It is able to perform diagnostic (open/short load/temperature) checks to detect LED failure and over-temperature on chip. The settings of all internal registers can be read out to verify written information at any time.

• 4-line Serial control + enable signal
• PWM dimming 0.1 to 100% global
• 6-bit LED brightness adjustment on each channel
• Diagnostic output on LED open and short for each channel
• Over-temperature protection and thermal feedback
• Read-back of all register settings
• Outputs may be connected in parallel to achieve more than 50mA into the load
• Slew limited switching reduces conducted and radiated noise (EMI)
• 3.5% Typical output current accuracy at 30mA
• 5μs Minimum PWM on time
• 5mA Maximum circuit current
