FUNCTIONAL DESCRIPTION
The circuit is designed to drive the two windings of a
bipolar stepper motor, and can be divided into two iden-
tical channels (channel 1 and channel 2) and protection
circuitry for overtemperature and undervoltage. The
functionality of a channel and protection circuitry is
presented in the following sections.
3.1
Power Bridge Operation
Each motor winding is driven by an H-type bridge
consisting of two N- and two P-transistors that allow the
current to flow in both winding directions, depending on
the value of the PHASE signal (Table 3-1). The
H-bridge can be set in five configurations that are
related to the digital inputs PHASE, I0 and I1, and to the
current sensed. These configurations are shown in
Table 3-2.
