負荷の駆動回路、それを用いたシステム、駆動回路の制御方法
Document Type and Number:
Japanese Patent JP7228335
Kind Code:
B2
Abstract:
Two control input pins INA and INB receive two control input signals from an external circuit. A logic circuit generates an internal signal SINT for indicating the state of an H-bridge circuit according to the two control input signals INA and INB. A pre-driver drives the H-bridge circuit based on the internal signal SINT. When the two control input signals INA and INB continue in a predetermined state for a predetermined judgment period of time, a standby circuit switches a driving circuit to a standby mode.
