4-ch MOTOR DRIVER FOR PORTABLE CD PLAYERS
--
YD5901
DESCRIPTION
This driver IC contains a 4ch H bridge driver and DC-DC converter control circuit on one chip, and was
developed for use in portable CD players. QFP-44 is used for the package, making it ideal for smaller sets.
FEATURES
*Built-in 4ch H Bridge Driver, and PWM Control of Load Drive Voltage is Made Possible by External
Components.
*DC-DC Converter Control Circuit on Chip.
* With Reset Output Inversion Output Pin.
*Empty Detection Level Can be Switched Between Rechargeable Battery and Dry Battery.
*Constant Current Charging; Current Value Can be Varied Using External Resistor.
*Built-in Power Transistor For Charging.
*Built-in Independent Thermal Shutdown Circuit.
