Reference Value
(a) Short-circuit test for BTL-mode operation after the main and standby switches are turned ON.
Conditions:
1
V
CC
= 10 to 16 V, R
L
= 4
and P
O
= 1 to 15 W (variable) for load short-circuit
2
V
CC
= 10 to 16 V, R
L
= 4
, Rg = 0 (no signal) for output-to-supply short-circuit
3
V
CC
= 10 to 16 V, R
L
= 4
, Rg = 0 (no signal) for output-to-ground short-circuit.
Z: impedance
j
: no device breakdown

(Note) Shorting the outputs to ground when muting is active can result in device breakdown.
.
Power supply positive surge
The power supply line positive surge breakdown margin has been increased by using the built-in overvoltage protection circuits
(V
CCX
= 28 V) to cut off all bias circuits/change the base-emitter reverse of the output stage. In other words, the breakdown
margin is being raised by changing output stage groups that operate as the V
CEO
(V
CER
) type to the V
CES
(V
CBO
) type.
