Optical disc ICs
4-channel driver and power controller
BA6893AK
The BA6893AK is a 4-channel driver and power supply that includes the reset, recharge, and shock detection circuits required for portable CD players on a single IC. The driver block power supply uses the on-chip switching regulator, making this component an ideal choice for low-power sets. FApplications Portable CD players FFeatures 1) Four H-bridge driver circuits. 2) DC to DC converter control circuit. 3) Reset circuit. 4) Shock .
