MPQ3326BGRE-AEC1-P

MPQ3326BGRE-AEC1-P is a 16-Channel, 80mA/Ch, LED driver with separated PWM/analogue dimming and I²C (default enable). It can operate from a wide 4.5V to 16V input voltage (VIN) range. The MPQ3326B applies 16 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 80mA. It integrates an I²C interface with up to 10 configurable I²C addresses via an external resistor. This means the MPQ3326B can support up to 10 cascaded ICs to drive the LED array. Each channel can be enabled or disabled through 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 ramp rate and phase shift can be configured to reduce EMI. Typical applications are automotive lights, automotive displays, instruments clusters, general industrial displays.
