change to normal power mode, write two commands to

the shutdown register. Set the FULLPD bit to 0 (other

bits in the shutdown register are ignored) on the first

command. A second command to this register acti-

vates the internal blocks.

TH1 and TH2 (Read/Write)

Set the external channel 1 and channel 2 high tempera-

ture ALARM thresholds by writing command bytes 20h

and 2Ch, respectively. Following the command byte,

write 12 bits of data to bits D11–D0. Read the high tem-

perature channel 1 and channel 2 ALARM thresholds

by writing command bytes A0h and ACh, respectively.

Following the command byte, read 12 bits of data from

bits D11–D0. Bits D15–D12 are don’t care. Temper-

ature data must be written and read in two’s-comple-

ment format, with the LSB corresponding to +0.125°C.

See Table 3. The POR value of the high temperature

ALARM threshold registers is 0111 1111 1111, which

corresponds to +255.875°C. See Table 4 for examples

of channel 1/channel 2 high and low temperature

threshold settings. See Figures 25 and 27 for ALARM

examples.

TL1 and TL2 (Read/Write)

Set the external channel 1 and channel 2 low tempera-

ture ALARM thresholds by writing command bytes 22h

and 2Eh, respectively. Following the command byte,

write 12 bits of data to bits D11–D0. Read the low tem-

perature channel 1 and channel 2 ALARM thresholds

by writing command bytes A2h and AEh, respectively.

Following the command byte, read 12 bits of data from

bits D11–D0. Bits D15–D12 are don’t care. Temper-

ature data must be written and read in two’s-comple-

ment format, with the LSB corresponding to +0.125°C.

See Table 5. The POR value of the low temperature

ALARM threshold registers is 1000 0000 0000, which

corresponds to -256.0°C. See Figures 25 and 27 for

ALARM examples.

IH1 and IH2 (Read/Write)

Set the channel 1 and channel 2 high sense voltage

ALARM thresholds by writing command bytes 24h and

30h, respectively. Following the command byte, write

12 bits of data to bits D11–D0. Read the high sense

voltage channel 1 and channel 2 ALARM thresholds by

writing command bytes A4h and B0h, respectively.
