Four-Channel BTL Driver for CD Players

ADE-207-330 (Z)

1st Edition

Dec. 2000

Description

HA13143 is a four-channel BTL driver IC for driving CD player actuators (focus and tracking) and motors

(carriage and spindle). It is ideal for small-profile players, since it requires few external parts and adopts a

compact, surface-mounting package (MP-26 DT).

Functions

• 4-channel BTL driver

• 5 V power-supply circuit

• Standby circuit

• Built-in protection circuits (surge current, TSD)

Features

• Four channels for driving the actuators and motors in a CD player

• High driving current

• Built-in protection against surge currents from other circuits or from short circuits

• Built-in thermal shutdown protection circuit with hysteresis

• Built-in 5 V power supply (uses external pnp transistor)

• Compact MP-26 DT surface-mounting package enabling use in small-profile players
