Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. The ASB is supplied in a pin dual in-line plastic package with copper heat-sink contact tabs. Logic Input Voltage Range.
Designed for bidirectional pulse-width modulated current control of. Always order by complete part number: The brake function can be safely used to dynamically brake brush dc motors.
Usually improved performance but not necessarily pin compatible. The information included herein is believed to be accurate and reliable. The PWM cycle repeats, maintaining the load current at the desired value see figure 2. Published on Sep View Download 1. Lead spacing tolerance is non-cumulative.
The use of sockets should be avoided as contact resistance can cause variations in the effective value of RS. This should be taken into account when determining the impedance of the external circuit that sets the reference voltage value. The dagasheet configuration enables easy attachment of a heat sink while fitting dztasheet standard printed wiring board layout. Competitive part numbers are shown in datasheft alpha-numerical order; letters are listed before numbers LX precedes L and CS is listed before CS Special power-up sequencing is not.
The current generated will depend on the mode of operation. The comparator output remains blanked until the voltage on CT reaches approximately 3. PSoC Family Datasheet Unity document suite datasheet 4 Documents. Typical Data is for design information only.

Special caution must be exercised in attempting to do a reverse cross. I Default Brake Current Limit. Datasueet optimal regulation of the load current, the above value for CT is recommended and datasehet value of RT can be sized to determine toff. Hauptwerk 4 Features Datasheet Documents. 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.
In forward or reverse mode the current-control circuitry limits the load current. Lead thickness is measured at seating plane or below.
These conditions can be tolerated but should be avoided.

The fixed off-time pulse duration is set by a userselected external RC timing network. Datasheey this case, a dc voltage on the REF input is used typically to limit the maximum load current. Datasheet pagepro en 4 Documents. Allegro products are not authorized for use as critical components in life-support devices or systems without express written approval.
I 50 V Output Voltage Rating. Each driver is tested separately. The load inductance causes the current to recirculate datashewt the source driver and flyback diode two-quadrant operation or slow decay. When the load current reaches ITRIP, the comparator resets a latch to turn off the selected sink driver. Similarly, when a transition of the PHASE input occurs, CT is discharged to near ground during the crossover datsaheet time the crossover delay time is present to prevent simultaneous conduction of the source and sink drivers.

These conditions can be tolerated but. In some instances, the competitive device is obsolete; in many instances, the suggested Allegro device features improved performance or specifications. I Internal Transient Suppression Diodes.
Internal circuit protection includes. The peak load current limit is.
