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.)
Min PWM ON Time:
5uS
Maximum circuit current:
5mA
Maximum clock frequency:
1250KHz
Operating temperature range: -40℃ to +105℃
●Features
AEC-Q100 Qualified (Note1)
Constant current output of up to 50mA per
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)
