PIN CONFIGURATION AND FUNCTION DESCRIPTIONS

NOTES

1. NC = NO CONNECT. THESE PINS ARE NOT CONNECTED

INTERNALLY AND SHOULD BE LEFT FLOATING.

2. CREATE A SIMILAR PAD ON THE PCB UNDER THE

EXPOSED PAD. SOLDER THE EXPOSED PAD TO

THE PAD ON THE PCB TO CONFER MECHANICAL

STRENGTH TO THE PACKAGE. DO NOT CONNECT

THE PADS TO AGND.

No Connect. These pins are not connected internally and should be left floating.

PULL_HIGH

Connect this pin to VDD for proper operation.

PULL_LOW

Connect this pin to AGND for proper operation.

RESET

Active Low Reset Input. Hold this pin low for at least 10 μs to trigger a hardware reset.

DVDD

On-Chip 2.5 V Digital LDO Access. Do not connect any external active circuitry to this pin. Decouple this pin

with a 4.7 μF capacitor in parallel with a ceramic 220 nF capacitor.

DGND

Ground Reference. This pin provides the ground reference for the digital circuitry.

7, 8

IAP, IAN

Analog Inputs for Current Channel A. This channel is used with the current transducers and is referenced in

this data sheet as Current Channel A. Connect these inputs in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to IAN.

9, 12

IBP, IBN

Analog Inputs for Current Channel B. This channel is used with the current transducers and is referenced in

this data sheet as Current Channel B. Connect these inputs in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to IBN.

13, 14

ICP, ICN

Analog Inputs for Current Channel C. This channel is used with the current transducers and is referenced in

this data sheet as Current Channel C. Connect these inputs in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to ICN.

15, 16

VP, VN

Analog Inputs for the Voltage Channel. This channel is used with the voltage transducer and is referenced as

the voltage channel in this data sheet. Connect these inputs in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to VN. This channel also has an internal PGA.

REFIN/OUT

On-Chip Voltage Reference Access. The on-chip reference has a nominal value of 1.2 V. An external reference

source with 1.2 V ± 8% can also be connected at this pin. In either case, decouple this pin to AGND with a

4.7 μF capacitor in parallel with a ceramic 100 nF capacitor.

Analog Input Common Pin for Current Channel D, Current Channel E, and Current Channel F. See the pin

descriptions for Pin 19, Pin 22, and Pin 23 for more details.

IFP

Analog Input for Current Channel F. This channel is used with the current transducers and is referenced in this

data sheet as Current Channel F. Connect this input in a single-ended configuration with a maximum signal

level of ±0.5 V with respect to IN.

IEP

Analog Input for Current Channel E. This channel is used with the current transducers and is referenced in

this data sheet as Current Channel E. Connect this input in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to IN.

IDP

Analog Input for Current Channel D. This channel is used with the current transducers and is referenced in

this data sheet as Current Channel D. Connect this input in a single-ended configuration with a maximum

signal level of ±0.5 V with respect to IN.
