BA6259N

Motor driver ICs 2-channel reversible motor driver BA6259N The BA6259N incorporates two reversible-motor drivers. FFeatures 1) Two reversible-motor driver circuits are built in. 2) Built-in thermal shutdown circuit. FBlock diagram 3) SIP10pin package. FAbsolute maximum ratings (Ta = 25_C) 504 Motor driver ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 12V) BA6259N FInput / output truth table FApplication example C2, C3 : Capacitors for preventing parasitic oscillation. Though the optimum capacitance depends on such PCB arrangement factors as the power supply circuit, motor characteristics, and conductor foil patterns, a range of 0.01X1µF is recommended. C4, C5 : Capacitors for preventing parasitic oscillation. They may or may not be required, depending on the PCB arrangement. A capacitance range of 0.01X10µF is recommended. 505 Motor driver ICs FControl pin equivalent circuit BA6259N (3) Due to the effects of capacitors C2XC5, the motor that is not being driven could be momentarily driven during mode switching. Check for this problem when designing your application. (4) It is recommendable to arrange your design so that voltage rises at VCC1 prior to VCC2 when turning on the power, and voltage falls at VCC1 after VCC2 when turning off the power. (5) Thermal shutdown circuit When the thermal shutdown circuit is activated, the output is left OPEN. The circuit is activated when the IC junction temperature rises above 170_C. The temperatur...
