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.
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 channe
◾ 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)
APPLICATIONs
◾ Automotive illumination
◾ Consumer electronics illumination
