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
