LED Driver IC

BD18377EFV-M

●General Description

The BD18377EFV-M is

●Key Specifications

serial input controlled

Input voltage range:

Output voltage range:

Output Current range/channel:

Output Current accuracy at 30mA:

Min PWM ON Time:

Maximum circuit current:

Maximum clock frequency:

Operating temperature range:

3.0V to 5.5V

0.5V to 10V

15mA to 50mA

3.5% (Typ.)

5uS

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.

5mA

1250KHz

-40℃ to +105℃

●Features

AEC-Q100 Qualified ^(Note1)

Constant current output of up to 50mA per

output channel.

●Package

HTSSOP-B20

W(Typ.) x D(Typ.) x H(Max.)

6.50mm x 6.40mm x 1.00mm

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)
