MPQ3323BGRE-AEC1-Z

MPQ3323BGRE-AEC1-Z is a 4-channel LED driver that can operate from a wide 4.5V to 16V input voltage (VIN) range. It applies four internal current sources in each LED string terminal. The LED current (ILED) of each channel is set by an external current-setting resistor. The maximum current for each channel is 320mA. It integrates an I²C interface with up to 10 configurable I²C addresses via an external resistor. This means the MPQ3323B can support up to 10 ICs cascaded ICs to drive the LED array. Each channel can be enabled or disabled via the I²C. It employs both separated pulse width modulation (PWM) dimming and analogue dimming for each LED channel, as well as 12-bit PWM dimming and 6-bit analogue dimming for each channel. The ILED ramping rate and phase shift can be configured to reduce EMI. It is used in applications such as automotive displays, instrument clusters, and general industrial displays.
