INPUT vs. OUTPUT

TA7259P/F/FG

VNF declares RF voltage drop.

In star-connection;

VNF =RF × IL

(IL: Coil current)

Refer to the diagram below.

When VIN+ and VIN- pins short-circuit or when V11 is equal to or greater than V12, rotating becomes zero torque.

However, zero torque status is also achieved by setting the FRS input pin to the specified voltage or open status. In

this case, power consumption is reduced.
