Data Sheet
4-CHANNEL MOTOR DRIVER WITH POWER CONTROLLER
General 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 component an ideal choice for
low-power sets. It is used in mini portable compact
