The LV5237JA is a 9-channel LED driver IC that is capable of switching between constant-current output and open drain output. Peak output current is IO max=100mA. It enables 2-wire/3-wire serial bus control (address designation) to be set arbitrarily using an external pin. Also possible are 9-channel LED ON/OFF control and the setting of the PWM luminance in 256 steps. Up to 81 driver ICs can be connected using the slave address setting pins.

• 9-channel output constant-current LED driver/open drain output LED driver
• (selected by using an external pin)
• Luminance adjustment using internal PWM control (256 steps)
• Selection of 2-wire / 3-wire serial bus control signals enabled
• Input Power supply supports 12 V
