Philips Semiconductors Preliminary specification
Power amplifier with load detection and
auto BTL/SE selection
TDA8586
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
Note
1. A large reverse current will flow, therefore external protection is needed (fuse and reverse diode).
