A4984SESTR-T Frequently Asked Questions (FAQ)
-
The maximum current rating of the A4984SESTR-T is 2A per phase, with a peak current rating of 2.5A.
-
The current limit on the A4984SESTR-T is set by the VREF voltage, which is connected to the REF pin. The current limit is calculated as ITRIP = VREF / (8 x Rs), where Rs is the sense resistor value.
-
The SLEEP pin is used to put the device into a low-power sleep mode, reducing the quiescent current to less than 1mA. This can be useful for power-saving applications.
-
The step mode on the A4984SESTR-T is configured using the MS1, MS2, and MS3 pins. The step mode can be set to full step, half step, quarter step, eighth step, or sixteenth step, depending on the desired microstepping resolution.
-
The DIAG pin is an open-drain output that indicates when the device is in an overcurrent or overtemperature condition. It can be used to alert the system to a fault condition.
