Advanced 12 Channel

Constant Current LED Driver IC

BD18378EFV-M

General Description

Key Specifications

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 SHORT for

each channel during PWM on & off time.

 True LED voltage measurement.

 Over Temperature Protection and Thermal

Feedback.

Applications

 Automotive illumination & ambient light

 Consumer electronics illumination

 Open Drain Fault indicator.

 Read-back of all register settings.

 Outputs can be connected in parallel to achieve

more than 50mA into the load.

 Slew Rate limited switching reduces

radiated Noise (EMI).

 Daisy chain compatible.
