2.6 Power Requirements

The XTR200EVM only accepts unipolar supplies within the voltage range of 8V to 60V.

The power supply connections for the XTR200EVM are provided through terminal block connector J1 or through the test points VSP and GND.

The 3.3V LDO is not necessary for the XTR200 to operate. The XTR200 has a built-in weak internal pullup resistors to 3.3V in the OD, MODE, and EF pins. The primary function of the onboard 3.3V LDO is to power the LED for visible fault detection from the EF pin.

To test the quiescent current of the XTR200, or see the LED light up during a power supply undervoltage event, TI recommends to separate the VSP from the 3.3V LDO by removing the housing receptacle on JP3 and powering up the 3.3V circuitry with a separate power supply. To use a separate power supply, connect the external power supply to pin 2 of JP3.
