Title:
MOTOR DRIVE CIRCUIT
Document Type and Number:
Japanese Patent JPH0690590
Kind Code:
A
Abstract:

PURPOSE: To reduce a through current, which pierces the output transistors on high potential side and low potential side, and also, to lessen the range of the output voltage generated by the through current by lowering the output saturation voltage of a bias circuit, which supplies the predriver circuit on low potential side with a bias current.

CONSTITUTION: The potential from a power source Vcc supplied to a bias circuit 240 is lowered by connecting a predriver circuit 220 on low potential side and a bias circuit 240, respectively, to the power source Vcc through a diode D1, which constitutes a voltage drop means 100a.
