AM5901A Datasheet | BCD Semiconductor

Description The AM5901A is a 4-channel motor driver with power controller that includes the reset, battery charge and reduced voltage detection circuits required for portable CD/MP3/VCD players on a single chip. This kind of IC is provided with lower startup voltage and power consumption than similar products, its driver block power supply uses on-chip switching regulator, making this ponent an ideal choice for low-power sets. It is used in mini portable pact disc players (CDP), portable mini disc players (MD), disc-man or other portable pact disc media. The AM5901A is available in PQFP-44 and LQFP-44 packages.
