DESCRIPTION

TOLERANT

NAME

NO.

AGND

Local analog ground for power stage, which must be connected to

the system ground.

ADR/FAULT

DIO

Dual function terminal which sets the LSB of the 7-bit I2C address to

"0" if pulled to GND and to "1" if pulled to DVDD. If configured to be

a fault output by the methods described in I²C Address Selection and

Fault Output, this terminal is pulled low when an internal fault occurs.

A pull-up or pull-down resistor is required, as is shown in the Typical

Application Circuit Diagrams. If pulled high (to DVDD), a 15-k

resistor must be used to minimize in-rush current at power up and to

isolate the net if the pin is used as a fault output, as described

above.

(1)

TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output

(2)

All pullups are 20-µA weak pullups and all pulldowns are 20-µA weak pulldowns. The pullups and pulldowns are included to assure

proper input logic levels if the terminals are left unconnected (pull-ups

→ logic 1 input; pulldowns → logic 0 input). Devices that drive

inputs with pullups must be able to sink 20 µA while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be

able to source 20 µA while maintaining a logic-1 drive level.
