L8229 General Description
This IC is designed to be very flexible in driving Stepping or DC motors.
By connecting to Vcc or to Gnd two program pins (pin 7 and 18) the user has the possibility to set up the device in different configurations.
1) The first configuration is an identical application of ST L6219 but with increased current. In this configuration L8229 provides a continuous current of the output stage up to 1.2A (1.5A peak).
2) The second configuration allows a functionality similar to previous one but with the possibility of choosing 8 different current levels to perform a more accurate stepping functionality. This is achieved by multiplexing the input pins dedicated to set the level of the current. Additionally the user can set the mixed mode decay for current recirculation.
3 and 4) The third and fourth configurations are intended to provide a very flexible programming for several parameters useful to drive different kind of Stepping and DC motors. This is achieved by means of a serial port interface that allows the user to configure the following parameters:
a) Current levels (32 values for each bridge).
b) Current direction.
c) Type of decay for Stepping motors (Mix/Slow) or for DC motors (Fast/Slow).
d) Vref input (Ext/Int).
e) Vref divider (:5/:10).
f) Blanking time (4 values).
g) Oscillator freq divider (4 values).
h) Off time (32 values).
i) Fast decay time (16 values).
j) Syncronous rectification.
The functionalities of the two configurations are identical except that the internal bit address (first bit of SPI words) can be programmed to be 1 or 0: this enables two different L8229 to share a common serial bus.
