MPQ3324 - LED Driver

General Description

The MPQ3324 is an 8-channel WLED driver that operates from a wide 4V to 16V input voltage range.

The MPQ3324 applies 8 internal current sources in each LED string terminal.

The LED current of each channel is set by an external current-setting resistor.

MPQ3324 8-Channel, 100mA/Ch, LED Driver with Separated PWM Analog Dimming and I2C Interface, AEC-Q100 DESCRIPTION The MPQ3324 is an 8-channel WLED driver that operates from a wide 4V to 16V input voltage range. The MPQ3324 applies 8 internal current sources in each LED string terminal. The LED current of each channel is set by an external current-setting resistor. Each channel has a maximum 100mA current (while VIN ≥ 4.5V). The device integrates an I2C interface. There are 10 different I2C addresses that can be configured via an external resistor. This means the MPQ3324 can support up to 10 ICs that have been cascaded to drive an LED array. Each channel can be enabled or disabled through the I2C.
