FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
Note If the operational amplifier is not used, it is possible
to connect all pins (E+, E-, OUT and VCC) to GND. In this
case, all of the four pins must be grounded.
+ 5.0 V VOLTAGE REGULATOR OUTPUT PIN (VDD)
The VDD pin is needed to place an external capacitor to
stabilize the regulated output voltage. The VDD pin is
intended to supply the embedded microcontroller. The pin is
protected against shorts to GND with an integrated current
limit (temperature shutdown could occur).
Important The VDD, EVDD, VDDA, and VREFH pins
must be connected together.
VOLTAGE REGULATOR AND CURRENT SENSE
AMPLIFIER GROUND PIN (AGND)
The AGND pin is the ground pin of the voltage regulator
and the current sense operational amplifier.
Important GND, AGND, VSS, EVSS, VSSA, and VREFL
pins must be connected together.
NO CONNECT PINS (NC)
The NC pins are not connected internally.
Note Each of the NC pins can be left open or connected
to ground (recommended).
