4 / 36 page  MP3326 – 16-CHANNEL LED DRIVER WITH I2C AND SEPARATED PDIM/ADIM MP3326 Rev. 1.0 www.MonolithicPower.com 4 1/4/2021 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2021 MPS. All Rights Reserved. PIN FUNCTIONS Pin # Name Description 1 RFSH/FLT Refresh signal output or fault flag. If FLTEN = 0, the RFSH/FLT pin outputs a synchronized signal set by the FRFSH register. If FLTEN = 1, the RFSH/FLT pin indicates a fault condition, and this pin is pulled low if a fault is triggered. 2 EN Enable. Pull EN low to disable the IC; pull EN high to enable the IC. 3 SCL I2C interface clock input. 4 SDA I2C interface data input. 5 ADDR I2C address setting. Connect a resistor to ADDR and GND to configure the 4LSB of the I2C address. There are 10 configurable addresses. 6 ISET LED current setting. Connect a current-setting resistor from this pin to ground to configure the current in each LED string. 7 LED1 LED channel 1 current input. Connect the LED channel 1 cathode to this pin. 8 LED2 LED channel 2 current input. Connect the LED channel 2 cathode to this pin. 9 LED3 LED channel 3 current input. Connect the LED channel 3 cathode to this pin. 10 LED4 LED channel 4 current input. Connect the LED channel 4 cathode to this pin. 11 LED5 LED channel 5 current input. Connect the LED channel 5 cathode to this pin. 12 LED6 LED channel 6 current input. Connect the LED channel 6 cathode to this pin. 13 LED7 LED channel 7 current input. Connect the LED channel 7 cathode to this pin. 14 GND Ground. 15 LED8 LED channel 8 current input. Connect the LED channel 8 cathode to this pin. 16 LED9 LED channel 9 current input. Connect the LED channel 9 cathode to this pin. 17 LED10 LED channel 10 current input. Connect the LED channel 10 cathode to this pin. 18 LED11 LED channel 11 current input. Connect the LED channel 11 cathode to this pin. 19 LED12 LED channel 12 current input. Connect the LED channel 12 cathode to this pin. 20 LED13 LED channel 13 current input. Connect the LED channel 13 cathode to this pin. 21 LED14 LED channel 14 current input. Connect the LED channel 14 cathode to this pin. 22 LED15 LED channel 15 current input. Connect the LED channel 15 cathode to this pin. 23 LED16 LED channel 16 current input. Connect the LED channel 16 cathode to this pin. 24 VIN Power supply input. VIN supplies the power to the IC, and must be locally bypassed. |
