1. This reset signal is activated by a decrease of VOUT1 voltage which can be due to an overload of pin OUT1

or by a lack of Input Voltage (VIN1).

2. The output short-circuit currents are tested one channel at time. During a short-circuit, a large consumption

of power occurs, but the thermal protection circuit prevents any excessive temperatures. A safe permanent

short-circuit protection is only guaranteed for input voltages up to 16 V.
