4-CH MOTOR DRIVER FOR

PORTABLE CD PLAYERS

DESCRIPTION

The UTC UA1538 contains a 4ch H bridge driver and

DC-DC converter control circuit on one chip, and was

developed for use in portable CD players.

LINEAR INTEGRATED CIRCUIT

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.

QFP-44-0.8

*Pb-free plating product number: UA1538L
