BD18378EFV-M
General Description
The BD18378EFV-M is a serial input controlled constant
current LED driver with 8 V output rating. 6 bit current
calibration is available for each output while a selected
PWM input performs dimming on the corresponding
output. The BD18378EFV-M is able to perform diagnostic
(open / short / temperature) checks to detect LED failure
and over temperature on chip. Fault detection is
performed also during LED deactivated state. The
settings of all internal registers can be read out to verify
written information at any time.
Features AEC-Q100 Qualified (Note1) Current capability: 50mA per output channel. 4-line SPI Control. External resistor current setting. Limp Home capability. PWM dimming 0.2-99.2% at 200Hz Diagnostic of all PWM inputs. Programmable output mapping to each PWM input. 6 Bit LED brightness adjustment on each channel. Diagnostic output on LED OPEN and SH...
