BD9202EFS Product details

Description

BD9202EFS is the LED driver IC which loads the step-up DCDC controller and the constant electric current driver of 8ch.

As for the constant electric current driver, PWM modulated light of 10bit gradation (1024stages) is possible with the register setting from 4 line serial interfaces.

Features

1)8ch constant electric current driver built-in Largest drive electric current 150mA/CH.
2 10bit gradation (1024 stages) modulated light is possible by register setting To input the standard CLK of PWM from outside is possible (BCT_SYNC_IN terminal) Because it is high output resisting pressure (60V), the multi-stage connection of LED is p ossi b le Detecting abnormal mode with LED opening detection 2)Step-up DCDC controller built-in 3) UVLO function 4) 4 line serial interface 5) HTSSOP-A4.
