LINEAR INTEGRATED CIRCUIT
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.
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.
