Monolithic Linear IC
LA6242H
For CD Player
4-channel Bridge (BTL) Driver
Overview
The LA6242H is a 4-channel motor driver IC for home and car CD players. It provides a pin for switching the channel 1
input.
Functions
• Four bridge-connected (BTL) power amplifier circuits
• IO max: 1A
• Built-in level shifter circuits
• Muting circuit (on/off control for all outputs)
• High output voltage (dynamic range): 6.5V (typical, channel 1 only)
• Built-in input operational amplifier (channel 1 only)
• Channel 1 input operational amplifier switching function
• Built-in regulator that uses an external PNP transistor and is set by the value of an external resistor.
• Built-in overheat protection (Thermal shutdown) circuit (Design guarantee)
