Title:
LOAD DRIVING CIRCUIT, PELTIER DEVICE SYSTEM, AND WARMTH GIVING APPARATUS
Document Type and Number:
Japanese Patent JP2019212994
Kind Code:
A
Abstract:
To achieve three states for each of one or more loads with one input.SOLUTION: A load driving circuit 10 comprises: a conversion circuit 2; and an output circuit 4. The conversion circuit 2 converts an input potential Vin of one input point 101 that can take three patterns of input potentials Vin into output values from two output points 102, 103 that each can output at least a binary. The output circuit 4 performs power supply to a load 1 according to the output values from the two output points 102, 103. The conversion circuit 2 changes the output values from the two output points 102, 103 according to the magnitude relationship between the input potential Vin and a reference potential Vref. The output circuit 4 switches, according to the output values from the two output points 102, 103, between a first mode of causing a current in a first direction into flow to the load 1, a second mode of causing a current in a second direction to flow into the load 1, and a third mode of not causing a current to flow into the load 1.SELECTED DRAWING: Figure 1
