BA6229

Motor driver ICs Reversible motor driver BA6229 The BA6229 is a monolithic IC used for driving reversible motors. The ICs contain a logic section by which brake and open modes can be set and an output power transistor by which forward and reverse operations are controlled. FFeatures 1) Built-in power transistor for motor driving (1.2A Max.). 2) Low quiescent current. (VCC=12V, IQ=1mA) 3) Wide range of operating supply voltage (8 X 23V). FBlock diagram 4) Interfaces with CMOS devices. 5) Four output modes: forward, reverse, stop (open), and brake. 6) Built-in diode absorbs surge currents. FAbsolute maximum ratings (Ta = 25_C) 411 Motor driver ICs FMeasurement circuit FApplication example BA6229 FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC1 = 12V) 412 Motor driver ICs FOperation notes (1) The quality of these products have been carefully checked; however, use of the products with applied voltages, operating temperatures, or other parameters that exceed the absolute maximum rating given may result in the damage of the IC and the product it is used in. If the IC is damaged, the short mode and open modes cannot be specified, so if the IC is to be used in applications where parameters may exceed the absolute maximum ratings, then be sure to incorporate fuses, or other physical safety measures. (2) Input pins Voltage should never be applied to the input pins when the VCC voltage is not applied to the IC. Similarly, when VCC is applied, the voltage ...
