DESCRIPTION
The UC3517 contains four NPN drivers that operate in two-phase
fashion for full-step and half-step motor control. The UC3517
also contains two emitter followers, two monostables, phase de-
coder logic, power-on reset, and low-voltage protection, making it
a versatile system for driving small stepper motors or for control-
ling large power devices.
The emitter followers and monostables in the UC3517 are config-
ured to apply higher-voltage pulses to the motor at each step
command. This drive technique, called “Bilevel,” allows faster
stepping than common resistive current limiting, yet generates
less electrical noise than chopping techniques.
