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.

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 ...
