BD18377EFV-M - 12 Channel Constant Current LED Driver

General Description

The BD18377EFV-M 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.

Key Features

  • -Q100 Qualified (Note1) Constant current output of up to 50mA per output channel. 4-line Serial Control + Enable Signal. PWM.

12 Channel Constant Current LED Driver IC BD18377EFV-M ●General Description The BD18377EFV-M 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. The BD18377EFV-M 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. ●Key Specifications Input voltage range: 3.0V to 5.5V Output voltage range: 0.5V to 10V Output Current range/channel: 15mA to 50mA Output Current accuracy at 30mA: 3.5% (Typ.
