Monolithic Power Systems’ (MPS’) MPQ7225 presents automotive designers with an AEC-Q100-qualified current sink LED driver that features 16 channels rated at up to 200 mA and adaptive feedback control to maximise system efficiency – in this case the output voltage of the output voltage pre-regulator is adjusted in real time to minimise the voltage across the channels to save power (300 mV typ. @ 200 mA).
The MPQ7225 comes in a 5 x 6-mm QFN package and is well suited for dynamic lighting displays thanks to 12-bit PWM dimming and 6-bit analogue dimming per channel. 16 individual MPQ7225 ICs can be cascaded to create a 256-channel solution with individual control of each channel. Since these lighting rigs may be operated at a distance from each other, MPS’ solution is compatible with a high-speed, CAN-type differential interface for robust sequencing.
Additional features include frequency spread spectrum to optimise EMC performance and various fault detection abilities to enhance functional safety.
