When both inputs 1 and 2 are set to low-level, outputs 1 and 2 are set to “OFF”. When input 1 is set to high-level and input 2 is set to low- level, output 1 is set to high-level and output 2 is set to low-level (forward rotation status). When input 1 is set to low-level and input 2 is set to high-level, output 1 is set to low-level and output 2 is set to high-level (reverse rotation). When both inputs 1 and 2 are set to high-level, both outputs 1 and 2 are set to low-level (brake status). The power supply (VCC) to the control circuit and the power supply (VCC’) for output are independently provided. The rotating speed of the motor can be therefore changed by using VCC and VCC’as different power supplies and by making VCC or VCC’ variable. In addition, built-in thermal protection circuit protects the IC from thermal destruction in case of abnormal condition such as motor blocking. IOH=-50mA IOH=-100mA VCC=VCC’=12V VI1=0V, VI2=2V or VI1=2V, VI2=0V However, indicates the junction temperature only in the case of VCC ≥7V. 5 Input Output Remarks IN1 IN2 LL HL LH HH “OFF” state “OFF” state HL LH LL O1 O2 No operation of IC ex Forward rotation ex Reverse rotation Brake LOGIC TRUTH TABLE |
