The ASW, for higher package power dissipation.

At the end of the RTCT interval, the drivers are re-enabled allowing the load current to increase again. Bizhub e datasheet 4 Documents.

ASW 데이터시트(PDF) – Allegro MicroSystems

Larger values of RS reduce the aforementioned effects but can result in excessive heating and power loss in the sense resistor. Because the kinetic energy stored in the motor and load inertia is being converted into current, which charges the VBB supply bulk capacitance power supply output and decoupling capacitancecare must be taken to ensure the capacitance is sufficient to absorb the energy without datashwet the voltage rating of any devices connected to the motor supply.

Leads indicated are internally one piece. This can have added benefits in bidirectional brush dc servo motor applications as the transfer function www. The PWM cycle repeats, maintaining the load current at the desired value see figure 2. Special power-up sequencing is not required. The lead configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout.

Lead thickness is measured at seating plane or below. Published on Sep View Download 1.

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 a3591sw decoupling capacitance.

An internally generated dead time prevents crossover currents that can occur when switching phase or braking. Datasheet 4 Download Report. The ASB is supplied in a pin dual in-line plastic package.

The fixed off-time pulse duration is set by a user- selected external RC timing network. Negative current is defined as coming out of sourcing the specified device terminal. When the device is re-enabled, CT is charged by the internal current source. The peak load current limit is. The information included herein is believed to be accurate and reliable.

These conditions can be tolerated but should be avoided. Before placing an order, the user is cautioned to verify that the information being relied upon is current. However, Allegro MicroSystems, Inc. The ASW, for higher package power dissipation requirements, is supplied in a pin single in-line power-tab package. Lead gauge plane is 0. Designed for bidirectional pulse-width modulated current control of. 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.


EP The ASB and ASW may be used for bidrectional control of bipolar stepper motors with continuous output currents to 2 A and peak start-up currents as high as 3. 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.

Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value.
