Frequently Asked Questions
What is the operating voltage range for this predriver?
It supports a wide range of operation voltages from 4V to 28V.
How does the unit detect motor lock, and can it recover automatically?
When locked, the LD/TACO pins are monitored for internal charging signals, triggering both an alarm output (AL) and automatic restart functions.
What specific parameters govern the auto-restart time (T)?
The auto-restart time is proportional to the external capacitance (C) connected to the LD pin.
Is this device suitable for all DC fan motor applications?
It is specifically suited as a predriver for DC cooling fan motors and locks motor protection using an open collector circuit.
