BA6247N

Motor driver ICs Reversible motor driver BA6246N / BA6247 / BA6247N / BA6247FP-Y The BA6246N, BA6247, BA6247N and BA6247FP-Y are monolithic ICs incorporating two reversible-motor drivers. The ICs differ in the control logic and output mode. FFeatures 1) Two reversible-motor drivers in each unit. 2) Built-in thermal shutdown circuit. 3) Output voltage can be set arbitrarily. 4) Available in a compact SIP10pin package (BA6246N, BA6247N) or a HSIP10pin package with radiation fins (BA6247). 5) Available in a HSOP25pin surface-mount package (BA6247FP-Y).

To secure the LOW level input, the interface to these pins should have a current-sink capability of at least 700 µ A (5V / 15kΩ 2). (3) The maximum input voltage is 6V. Make sure that the input will not exceed this value. Also when the voltage VCC is not ...
