EVQ3326-R-00A

EVQ3326-R-00A is an evaluation board designed for the MPQ3326, a 16 channel WLED driver that can operate from a wide 4V to 16V input voltage range. The MP3326 applies 16 internal current sources in each LED string terminal. The LED current of each channel is set by an external current-setting resistor. The maximum current for each channel is 50mA (VIN ≥ 4.5V). The device integrates an I2C interface with up to 10 configurable I2C addresses via an external resistor. This means MPQ3326 can support up to 10 cascaded ICs to drive the LED array. Each channel can be enabled or disabled through the I2C. MPQ3326 employs both separated PWM dimming and analogue dimming for each LED channel, as well as 12bit resolution PWM dimming and 6bit analogue dimming for each channel. Applications include automotive lights, automotive displays, instruments clusters and general industrial displays. It is available in a QFN-24 (4mmx4mm) package.
