4-ch BTL Motor Driver for CD Players MM1469
4-ch BTL Motor Driver for CD Players
Monolithic IC MM1469
Outline
This IC is a 4-ch BTL driver developed for driving motors and actuators for CD players.
With built-in 3.3V (MM1469PH) or 5.0V (MM1469XH) regulator and general-purpose op-amp, it supports a
variety of applications.
Features
1. External resistor allows gain adjustment.
2. Few external parts
3. Built-in 3.3V or 5.0V regulator (external PNP-Tr required)
4. Built-in general-purpose op-amp
5. Built-in thermal shutdown circuit
Package
HSOP-28A
Applications
1. CD radio cassette players
2. VCD
