Help For Power Connection of TPS25200

Other Parts Discussed in Thread: TPS25200

Hello,

I am going to use TPS25200 in my motor drive circutry in order to limit current and also sense stall of dc motor.
The problem is MCU(digital) and motor driver parts' power systems are isolated.

Which GND should i use for pull down resistors?

Another question is, i will drive enable pin from an I/O of MCU. Do i need pull-up resistor at Enable pin?

Thank You.

    RILIM (R39) should connect directly between pin 2 and pin 5 through a good, low impedance connection (ground plane is preferred). Pin 5 should be connected to the power pad (pin 7).

    The EN pin needs to be driven high or low but not left floating.

    Refer to the TERMINAL FUNCTIONS table on page 3 of the datasheet for more information regarding pin connections.
