LV5237JA

LV5237JA Advance Information Bi-CMOS IC 9-channel LED Driver www.onsemi.com Overview 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. Function SSOP24 (225mil)  9-channel output constant-current LED driver/open drain output LED driver (selected by using an external pin) Supports separate ON/OFF setting for each LED output, high withstand voltage (VOUT<42V)  In the constant-current mode (OUTSCT: L), the reference current is set by the value of resistor connected to the external pin (RT1). Built-in D/A (5 bits) for switching current level … 0.86mA to 31.24mA (RGB drive) Consta...
