BD18377EFV-ME2

12 Channel Constant Current LED Driver IC BD18377EFV-M General Description Key Specifications The BD18377EFV-M is a serial input controlled Input voltage range: 3.0V to 5.5V constant-current LED driver with 10V output rating. 6 bit Output voltage range: 0.5V to 10V current calibration is available for each output while a Output Current range/channel: 15mA to 50mA global PWM performs dimming on all outputs Output Current accuracy at 30mA: 3.5% (Typ.) simultaneously. The BD18377EFV-M is able to perform Min PWM ON Time: 5uS diagnostic (open / short load / temperature) checks to Maximum circuit current: 5mA detect LED failure and over temperature on chip. The Maximum clock frequency: 1250KHz settings of all internal registers can be read out to verify Operating temperature range: -40 to +105 written information at any time. Features (Note1) AEC-Q100 Qualified Package W(Typ.) x D(Typ.) x H(Max.) Constant current output of up to 50mA per HTSSOP-B20 6.50mm x 6.40mm x 1.00mm output channel. 4-line Serial Control + Enable Signal. PWM dimming 0.1-100% 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). Daisy chain compatible with BD18377EFV-M and/or BD8377FV-M (12ch LED driver IC). (Note1: Operating Temperature Grade 2) Figure 1.
