The current generated will depend on the mode of operation. Each driver is tested separately. Larger values of RS reduce the aforementioned effects but can result dataaheet excessive heating and power loss in the sense resistor. Pagescope mobile datasheet 4 Documents. PSoC Family Datasheet Usually improved performance but not necessarily pin compatible.
The ASB is supplied in a pin dual in-line plastic package with copper heat-sink contact tabs. Leads indicated are internally one piece. The lead configuration enables. For more information regarding load current regulation, see below. Monicon 4 channel datasheet Documents. Similar to when braking the motor dynamically, abrupt changes in the direction of a rotating motor produce a current generated by the back EMF. Output current rating may be limited by duty cycle.

Bizhub e datasheet 4 Documents. An internally generated dead time prevents crossover currents that can occur when switching phase or braking.
When the device is re-enabled, CT is charged by the internal current source. MP in Dimensions in Millimeters for reference only The ASB is supplied in a pin dual in-line plastic package. These conditions can be tolerated but. A user-selectable blanking window prevents false triggering of the PWM current control circuitry.
These conditions daatasheet be tolerated but should be avoided. I 50 V Output Voltage Rating. These conditions can be tolerated but should be avoided. The value of toff can be chosen for optimization of these parameters. Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. This is intended only to protect the device from failures due to excessive junction temperatures and should not imply that output short circuits are permitted.
When the load current reaches ITRIP, the comparator resets a latch to turn a351sw the selected sink driver.
The lead configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout. When the PWM latch is reset by the current comparator, the voltage on the RC terminal will begin to decay from approximately 3 volts. Special power-up sequencing is not.
If so, the PWM cycle will repeat, limiting the load current to the desired value. Before placing an order, the user is cautioned to verify that the information being relied upon is current. The lead configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout.

The peak load current limit datashete. The load inductance causes the current to recirculate through the source driver and flyback diode two-quadrant operation or slow decay. After the crossover delay, CT is charged by an internal current source of approximately 1 mA.
Published on Sep View Download 1. The fixed off-time pulse duration is set by a user- selected external RC timing network. Datasheet 4 Download Report. At the end of the RTCT interval, the drivers are re-enabled allowing the load current to increase again. Ddatasheet Temperature, T J Internal circuit protection includes thermal x3951sw with hysteresis, transient suppression diodes, and crossover-current protection.
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. The information included herein is believed to be accurate and reliable. This directly relates to the limitations imposed by the VREF input 2. MAA in Dimensions in Millimeters for reference only 16 0. The ASW, for higher package power dissipation.
