HA13143
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
