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).

4) Interfaces with CMOS devices.
5) Four output modes: forward, reverse, stop (open),
and brake.
6) Built-in diode absorbs surge currents.FBlock diagram

FOperation notes
(1) The quality of these products have been carefully
checked; however, use of the products with applied voltages, operatingtemperatures, 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 modescannot
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) Inputpins
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 on each input pin should be
less than VCC andwithin the guaranteed range for 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 the back-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
