The current generated will depend on the mode of operation. Read more about the condition. Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months. 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 low current levels.

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

Because the kinetic energy stored in the motor and load inertia is being converted into current, which charges the V BB supply bulk capacitance power supply output and decoupling capacitancecare must full-beidge taken to ensure the capacitance is sufficient to absorb the energy without exceeding the voltage rating of any devices connected to the motor supply.

The peak load current limit is set by the user s selection of an input reference voltage and external sensing resistor. A brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable.

When the load current is increasing, slow decay mode is used to limit the switching losses in the device and iron losses in the motor.

A Full-Bridge PWM Motor Driver – PDF

A user-selectable blanking window prevents false triggering of the PWM current-control circuitry. The internal circuitry compares the voltage across the external sense resistor to the voltage on the reference input terminal REF resulting in a transconductance function approximated by: Refer to eBay Return policy for more details.


It will take working days weeks to receive for most area. Please note the delivery estimate is greater than 8 business days. The SP74 is used More information. Date of status change: During braking, with the MODE input low, the internal current-control circuitry is disabled. This classification indicates that sale of this device is currently restricted to existing customer More information. Two regulated current ports are designed More information. The brake circuit turns off both source drivers and turns on both sink drivers.

The MODE input determines whether the PWM current-control circuitry operates mohor a slow current-decay mode only the selected source driver switching or in a fast current-decay mode selected source and sink switching.
