Title:
LOAD DRIVE CIRCUIT, SYSTEM USING SAME, AND METHOD FOR CONTROLLING DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/174267
Kind Code:
A1
Abstract:
Two control input pins INA, INB receive two control input signals from the outside. Corresponding to the two control input signals INA, INB, a logic circuit 110 generates an internal signal SINT that instructs the state of an H bridge circuit 130. A pre-driver 120 drives the H bridge circuit 130 on the basis of the internal signal SINT. When the two control input signals INA, INB are held in a predetermined state for a predetermined determining time, a standby circuit 160 shifts a drive circuit 100 to be in standby mode.
