prior to the L6239 shutdown at the Thermal Shut-
down level.
Once the Thermal SHutdown is triggered the
spindle is tristated and the chip is reset (although
the serial interface can still be used). No braking
functiontaken place.
The chip remains in this state with the serial inter-
face availablefor access
Once the device falls below the Thermal Warning
temperature, the L6239 output stage is no longer
tristated.
If there is still sufficient motion in the motor, the
μ
P has the opportunutyto resynchronizethe out-
put
NegativeVoltage Regulator Support
This device includes support for a negative volt-
age supply. The regulator uses a regulation tech-
nique, that generates an external negative volt-
age, but does not require an negative power
supply. the diagram below shows the circuitry in-
cluded in the L6239 to supportthe Regulator.
The more lightly colored circuitry is the recom-
mended external circuitry that actually creates the
negativevoltage.
The circuit has been designed so that all external
componentsa can be inexpensive. For example,
the transistor needs only to be a 2N@()&A and
the diode a 1N4148.
