Motor Driver ICs
4-channel BTL driver for CD players
AM1469 V33/V50
The AM1469 is a 4-channel BTL driver for CD player motors and actuators. An internal 3.3V/5.0V
regulator and standard op amp are provided for variety of applications.
Applications
1. CD player
2. VCD player
3. DVD player
Features
1) HSOP28 package with good thermal
performance
2) Few external parts.
3) External resistor allows gain adjustment.
4) V33 -- 3.3V regulator.
V50 -- 5.0V regulator
(requires attached PNP transistor)
5) Internal standard operational amplifier.
6) Built-in thermal shutdown circuit.
