CIRCUIT DESCRIPTION
The ZN409CE incorporates a precision dual voltage
source providing 1.5V for internal use and 2.2V for external
circuit requirements.
The input circuit is a Schmitt trigger allowing servo opera-
tion independent of edge speed, as obtained from the re-
ceiver-decoder.
Output from the Schmitt trigger is fed to the deadband and
monostable circuits. The deadband circuit prvides a
prgrammable area of insensitivity to input pulse in order to
eliminate hunting and overshoot. Dynamic feedback can be
used to reduce the width of the deadband to acceptable levels,
and to maintain correct servo operation.
The monostable circuits provide the inputs to the pulse
comparison circuit which determines direction and amount of
drive required to reach the new position. The output drive is
also controlled by the pulse expansion circuit. This circuit
ensures that a stationary motor will start rotating without
drawing full stall current. This gives much improved battery
life.
