WIPO Patent Application WO/2019/135392
Kind Code:
A1
Abstract:
This multiple-output load driving device is provided with: a plurality of output terminals (OUT1 to OUT4) for respectively outputting output current to a plurality of loads (Z1 to Z4); a control unit (8) that selects either a non-DC current mode for setting the output current to be non-DC current or a DC current mode for setting the output current to be DC current; and a first terminal (MSET2). If a signal of a LOW level is supplied to the first terminal, the non-DC current is outputted from all the output terminals in the case of the non-DC current mode. If a signal of a HIGH level is supplied to the first terminal, the DC current is outputted from a prescribed one of the output terminals (OUT4) whereas the non-DC current is outputted from the output terminals (OUT1 to OUT3) in the case of the non-DC current mode.
