The lead configuration enables easy attachment of a heat sink while fitting a standard printed wiring board layout.

This directly relates to the limitations imposed by the VREF input 2. Internal circuit protection includes.

The information included herein is believed to be accurate and reliable. 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 exceeding the voltage rating of any devices connected to the motor supply.

Bizhub 25e datasheet 4 Documents. Datasheet pagepro en 4 Documents. When the device is re-enabled, CT is charged by the internal current source. Fixed Off-Time Selection With increasing values of toff, switching losses decrease, low-level load-current regulation improves, EMI is reduced, the PWM frequency will decrease, and ripple current will increase.

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. In internal PWM applications, only datasheett two top-side flyback diodes need be added. At the end of the RTCT interval, the drivers are re-enabled allowing the load current to increase again. When the load current reaches ITRIP, the comparator resets a latch to turn off the selected sink driver. 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 datassheet case of ENABLE PWM control which produces a discontinuous current at lowcurrent levels.

Hauptwerk 4 Features Datasheet Documents. Fatasheet ASB is supplied in a pin dual in-line plastic package with copper heat-sink contact tabs. Junction Temperature, T J Similar to when braking the motor dynamically, abrupt changes in the direction of a rotating motor produce a current generated by the back EMF.

If so, the PWM cycle will repeat, limiting the load current to the desired value. These conditions can be tolerated but. When the voltage on the RC terminal reaches approximately 1. The fixed off-time pulse duration is set by a userselected external RC timing network.

The brake function can be safely used to dynamically brake brush dc motors. Output current rating may be limited by duty cycle.

Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. Negative current is defined as coming out of sourcing the specified device terminal. The lead configuration enables.

The current generated will depend on the mode of operation. Usually improved performance but not necessarily pin compatible. For more information regarding load current regulation, see below.
