Reserved.
4
Bit stream
R/W
1 = the current sense ADC reading is output on the SHAREo pin. This bit stream can be used for
analog current sharing.
0 = the digital share bus signal is output on the SHAREo pin. This signal can be used for digital
current sharing.

R/W
1 = Reserved.
0 = CS2 reading used for current share.
[2:0]
Share bus
bandwidth
R/W
These bits determine the amount of bandwidth dedicated to the share bus. A value of 000 is the lowest
possible bandwidth, and a value of 111 is the highest possible bandwidth. The slave is incremented
by 1 LSB per share bus transaction (eight data bits plus start and stop bits). The master is decremented
by N LSBs per share bus transaction, where N is the value of Register 0x2A[7:4].

Table 42. Register 0x2A—Share Bus Setting
Bits
Bit Name
R/W
Description
[7:4]
Number of bits
dropped by master
R/W
These bits determine how much a master device reduces its output voltage to maintain current
sharing. For more information, see the description of Bits[2:0] in Register 0x29.
[3:0]
Bit difference
between master
and slave
R/W
These bits determine how closely a slave tries to match the current of the master device. The
higher the setting, the larger the voltage difference that satisfies the current sharing criteria.

Bits
Bit Name
R/W
Description

Gain polarity
R/W
1 = negative gain is introduced.
0 = positive gain is introduced.
[6:0]
Gain trim
R/W
This register calibrates the RTD ADC gain. It calibrates for errors in the ADC.

Both the software PS_ON bit and the hardware PSON pin must be enabled
before the ADP1046AW is enabled.

R/W
Software PS_ON bit.
0 = power supply off.
1 = power supply on.
