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)
Constant current (IO max=100mA) for full-color
LEDs  9 channels
 In the open drain mode (OUTSCT: H), high current drive
(IO max=100mA)  9 channels
 In the constant-current mode (OUTSCT: M)
Only RGB3 is open drain (IO max=100mA)
 Luminance adjustment using internal PWM control (256 steps), It copes with independent PWM control for each
LED output
 8-bit PWM luminance dimming (0% to 99.6%)
 3-phase PWM
 Selection of 2-wire/ 3-wire serial bus control signals enabled (switching using an external pin)
 Schmitt trigger input (3.3V/5V)
 Slave addressing (4 bits, connection of up to 81 driver ICs possible)
 Input Power supply supports 12V
 Internal reference output terminal (5V)
 Low current consumption
 Output malfunction protection circuits (thermal protection function, UVLO detection protection function, Power
on RESET)
