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