BLOCK DIAGRAM
The NJM3776 is a switch-mode (chopper), constant-current
controller intended for controlling external transistors in a high
current stepper motor application. The NJM3776 has two channels,
one for each winding of a two-phase stepper motor. The NJM3776
is equipped with a Disable input to simplify half stepping operation.
The NJM3776 contains a clock oscillator, which is common for both
driver channels, a set of comparators and flip-flops implementing
the switching control, and two output sections each containing four
outputs, two source and two sink, intended to drive an external H-
bridge. Voltage supply requirements are +5 V for logic and +10 to
+45 V for the outputs.
