00W015A Reversible Motor Driver BA6920FP-Y Description Dimension(Units:mm) The BA6920FP-Y is an IC for small DC motor drive which has a wide operating voltage range. It has four output modes such as forward, reverse, stop and brake. When the motor is stopped, all circuits turn off automatically. A power save circuit that reduces current consumption and a power save terminal is included. This IC has 34V maximum operating voltage, so that it is useful for wide varieties of applications. HSOP25 Features 1)Wide operating voltage range : 6.5~34V 2)Can be operated directly by TTL and CMOS 3)Low power consumption while the motor is stopping due to built-in power save circuit 4)Output high voltage can be set externally by VREF pin. 5)Built-in surge absorbing diode 6)Built-in TSD (Thermal shut down ) circuit 7) A signal ground and a power ground are provided separately, so that reversible/variable speed control is available by adding an electronic governor.
