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.
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 to low if a protection is triggered. Meanwhile,
the corresponding fault register is set.
The MPQ3324 is AEC-Q100 qualified, and is
available in QFN-24 (4mmx4mm).
