Special caution must be exercised in attempting to do a reverse cross. Datasheet 4 Download Report. This should be taken into account when determining the impedance of the external circuit that sets the reference voltage value. The fixed off-time pulse duration is set by a userselected external RC timing network.

Special power-up sequencing is not required. I Internal Thermal Shutdown Circuitry. In addition to determining the fixed off time of the PWM control circuit, the CT component sets the comparator blanking time. An internal under-voltage lockout circuit prevents simultaneous conduction of the outputs when the device is powered up or datassheet down. Lead thickness is measured at seating plane or below.

Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. However, if the back-EMF voltage is large and there is no PWM current limiting, then the load current can increase to a value that approaches a39551sw locked rotor condition.

The dwtasheet configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout. In some instances, the competitive device is obsolete; in many instances, the suggested Allegro device features improved performance or specifications.

This can have added benefits in bidirectional brush dc servo motor applications as the transfer function www. Before placing an order, the user is cautioned to verify that the information being relied upon is current.

This simplifies the servo-control loop because the transfer function between the duty cycle on the PHASE input and the average voltage applied to the motor is more linear than in the case of ENABLE PWM control which produces a discontinuous current at lowcurrent levels. When the PWM latch is reset by the current comparator, the voltage on the RC terminal will begin to decay from approximately 3 volts. For optimal regulation of the load current, the above value for CT is recommended and the value of RT can be sized to determine toff.

When the device is enabled, the internal current-control circuitry will be active and can be used to limit the load current in the normal internal PWM slow-decay or two-quadrant mode of operation. This value ensures that the blanking time is sufficient to avoid false trips of the comparator under normal operating conditions.

Hauptwerk 4 Features Datasheet Documents. A user-selectable blanking window prevents false triggering of the PWM. For more information regarding load current regulation, see below. Datasheet magicolor en 4 Documents. A user-selectable blanking window prevents false triggering of the PWM current control circuitry.

When the direction of the motor is changed abruptly, the kinetic energy stored in the motor and load inertia will be converted into current that charges the VBB supply bulk capacitance power supply output and decoupling capacitance.

For new system de. The lead configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout. Exact replacement in all applications is not guaranteed and the user should compare the specifications of the competitive and recommended Allegro replacement. In internal PWM applications, only the two top-side flyback diodes need be added.
