14.2 Output current limiting
The peak output current is internally limited above a level of 3 A minimum. During normal
operation the output current should not exceed this threshold level of 3 A, otherwise the
output signal will be distorted. The peak output current in BTL can be estimated using
Equation
Where:
I
O
Fig 26. BTL output power as function of supply voltage: THD = 0.5 %. 3 A
Fig 27. BTL output power as function of supply voltage: THD = 10 %. 3 A
