(1)

RTI = referred-to-input.

(2)

The supply voltage range maximum is 36 V, but the reference voltage cannot be higher than 18 V.

(3)

See the Integrated Shunt Resistor section for additional information regarding the integrated current-sensing resistor.

(4)

The internal shunt resistor is intended to be used with the internal amplifier and is not intended to be used as a stand-alone resistor. See

the Integrated Shunt Resistor section for more information.

(5)

See Figure 30 and the Layout section for additional information on the current derating and layout recommendations to improve the

current handling capability of the device at higher temperatures.
