Please note the delivery estimate is greater than 8 business days. Generally, larger values of R S reduce the aforementioned effects but can result in excessive heating and power loss in the sense resistor. These values ensure that the blanking time is sufficient to avoid false trips of the comparator under normal operating conditions. Therefore, care should be taken to ensure that the motor s current does not exceed the ratings of the device. The MODE input determines whether the PWM current-control circuitry operates in a slow current-decay mode only the selected source driver switching or in a fast current-decay mode selected source and sink switching.

In fast currentdecay mode, the selected sink and source driver pair are disabled; the load inductance causes the current to flow from ground to the load supply via the ground clamp and flyback diodes.
