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 of 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.
The MPQ3324 employs both separated PWM dimming and analog dimming for each LED channel, with a 12-bit PWM dimming resolution and 6-bit analog dimming for each channel. To
optimize EMI and EMC performance, The LED current ramping rate and phase shift can be configured.
The MPQ3324 can output a refresh signal from the RFSH/FLT pin. The refresh signal frequency can be set via the I2C. Integrated protections include open-load protection, short-load protection, and overtemperature protection (OTP). The fault indicator pulls too low if protection is triggered. \Meanwhile, the corresponding fault register is set.
The MPQ3324 is AEC-Q100 qualified and is available in QFN-24 (4mmx4mm).
