CXA2534Q is a 4-channel H-bridge motor driver IC designed for portable CD systems. It has a built-in DC to DC converter controller that allows voltage step-up to typically 3.2 V; this voltage can be used to power the system DSP, SSP and micro-controller. In addition, CXA2534Q also provides a PWM regulated power supply to the H-bridge output stage so as to ensure high efficiency.
