About This Product

■Summary

The MPQ3323B is a 4-channel LED driver that operates over a wide input voltage (VIN) range of 4.5V to 16V. MPQ3323B employs four internal current sources on each LED string terminal. The LED current (ILED) for each channel is set by an external current setting resistor. The maximum current for each channel is 320mA. The MPQ3323B integrates a digital interface with up to 10 programmable digital interface addresses via external resistors. This means the MPQ3323B can support up to 10 cascaded devices to drive an LED array. Each channel can be enabled or disabled through the digital interface. The MPQ3323B employs both independent pulse width modulation (PWM) and analog dimming for each LED channel, as well as 12-bit PWM dimming and 6-bit analog dimming for each channel. Configurable ILED lamp rate and phase shift to reduce EMI. MPQ3323B can output refresh signal from RFSH/FLT pin. The refresh signal frequency (fREFRESH) can be set via the digital interface. Extensive protection features include LED open protection, LED short circuit protection, and overtemperature protection (OTP). The device also has a fault indicator. When the protection function is activated, the fault RFSH/FLT goes low and the corresponding fault register is set. The MPQ3323B is AEC-Q100 qualified and available in a QFN-24 (4mm x 4mm) package.
