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 anoutput 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 surgecurrents.

FOperation notes (1) The quality of these products have been carefully checked; however, use of the products with applied voltages, operating temperatures, orother 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, soif 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 shouldnever be applied to the input pins when the VCC voltage is not applied to the IC. Similarly, when VCC is applied, the voltage on each input pin should be less than VCC and within the guaranteed rangefor the electrical characteristics. (3) Back-rush voltage Depending on the ambient conditions, environment, or motor characteristics, the back-rush voltage may fluctuate. Be sure to confirm that theback-rush voltage will not adversely affect the operation of the IC. (4) Large current line Large currents are carried by the motor power supply and motor ground for these ICs. Therefore, the layout...
