Basic operation
When the output current (M (+) or M (-)、Isink or Isource) is up to the I
is controlled by the input signals. When it exceeds the detection current, the output assumes a
switching waveform as shown in Figure 1.
Detailed explanation
The output current is detected by monitoring the V
connects to one of the output transistors and leads to the short-circuit protection circuit. When a
current exceeding the I
short-circuit protection circuit is activated. This circuit contains a timer. When overcurrent condition
continues for 20 ms (typically) , the protection circuit places the output in high-impedance mode and, 80
ms (typically) later, returns the IC to ON mode. The switching-waveform output is repeated until
overcurrent condition is no longer present.
