1, 3

GNDISO

Ground for the Isolated DC-to-DC Converter, Connected to the GNDISO Paddle.

VDDISO

DC-to-DC Converter Voltage Output. VDDISO requires a low ESR 100 nF bypass capacitor

connected to GNDISO.

AVDD

Power Supply for the Isolated Side. AVDD requires 4.7 µF and 100 nF bypass capacitor to

AGND.

5, 11

AGND

Ground Reference.

ALDOOUT

1.8 V Output of Analog LDO Regulator. Decouple the ALDOOUT pin with a 4.7 µF capacitor

in parallel with a ceramic 100 nF capacitor to AGND, Pin 5. Do not connect the external load

circuitry to the ALDOOUT pin.

No Connect. The NC pin has an internal connection. Leave the NC pin floating or tie it to Pin 8.

No Connect. The NC pin has an internal connection. Leave the NC pin floating or tie it to Pin 7.

V2P

Positive Analog Input for the V2 Voltage Channel. The voltage channels are used with the voltage

transducers. V2Pand V2M are differential voltage inputs with a maximum single-ended signal

level of ±500 mV with respect to the VxM pins for specified operation. Use the V2P and V1P

pins with the related input circuitry, as shown in Figure 27. If the V2 voltage channel is not used,

connect the V2P pin to the V2M pin.

V2M

Negative Analog Input for the V2 Voltage Channel.

V1P

Positive Analog Inputs for the V1 Voltage Channel. V1P and V1M are differential voltage inputs

with a maximum single-ended signal level of ±500 mV with respect to the VxM pins for specified

operation. Use the V1P and V2P pins with the related input circuitry, as shown in Figure 27. If the

V1 voltage channel is not used, connect the V1P pin to the V1M pin.

V1M

Negative Analog Input for the V2 Voltage Channel.

REFOUT

Voltage Reference Output. The REFOUT pin provides access to the on-chip voltage reference.

The on-chip reference has a nominal value of 1.25 V. Decouple the REFOUT pin to AGND, Pin

11, with a 4.7 µF capacitor in parallel with a ceramic 100 nF capacitor. Do not connect external

load circuitry to the REFOUT pin.

Negative Analog Input for the Current Channel. The current channel is used with shunts. IM and

IP are pseudo differential voltage inputs with a maximum differential level of ±31.25 mV. Use the

IM and IP pins with the related input circuitry, as shown in Figure 27.

Positive Analog Input for the Current Channel.

IRQ

Interrupt Request Output. The IRQ pin is an active low logic open drain output with weak internal

pull-up resistor.

Zero-Crossing Output Pin. The ZX pin must float when unused.
