PRELIMINARY TECHNICAL DATA

internal and external temperature sensors as it cycles

through all possible measurement channels. The two tem-

perature channels are measured each time the part runs a

round robin sequence. In round robin mode the part is

continously measuring.

MONITORING

The ADT7316/17/18 also has the capability of monitoring

’

s own power supply. The part measures the voltage on

’

s V

pin to a resolution of 10 bits. The resultant value

is stored in two 8-bit registers, the two LSBs stored in

tion of just doing a one byte read if 10-bit resolution is not

important. The measured result is compared with V

HIGH

and V

LOW

limits. If the V

interrupt is not masked out

then any out of limit comparison generates a flag in Inter-

rupt Status 2 Register and one or more out-of-limit results

will cause the INTERRUPT output to pull either high or

low depending on the output polarity setting.

Measuring the voltage on the V

pin is regarded as moni-

toring a channel. Therefore, along with the Internal and

External temperature sensors the V

voltage makes up

the third and final monitoring channel. You can select the

channel for single channel measurement by setting Bit

C4 = 1 and setting Bit 0 to Bit 2 to all 0

’

s in Control

Configuration 2 register.

When measuring the V

value the reference for the ADC

is sourced from the Internal Reference. Table 2 shows the

data format. As the max V

voltage measurable is 7 V,

internal scaling is performed on the V

voltage to match

the 2.25V internal reference value. Below is an example of

how the transfer function works.

= 5 V

ADC Reference = 2.25 V

1 LSB = ADC Reference / 2^10 = 2.25 / 1024 =

2.197mV

Scale Factor = Fullscale V

/ ADC Reference = 7 / 2.25

= 3.11

Conversion Result = V

/ ((7/Scale Factor) x LSB size)

= 5 / (3.11 x 2.197mV)

= 2DBh

ON-CHIP REFERENCE

The ADT7316/17/18 has an on-chip 1.2 V band-gap

refernece which is gained up by a switched capacitor am-

plifier to give an output of 2.25 V. The amplifier is only

powered up at the start of the conversion phase and is

powered down at the end of conversion. On power-up the

default mode is to have the internal reference selected as

the reference for the DAC and ADC. The internal refer-

ence is always used when measuring the internal and ex-

ternal temperature sensors.

ROUND ROBIN MEASUREMENT

On power-up the ADT7316/17/18 goes into Round Robin

mode but monitoring is disabled. Setting Bit C0 of Con-

figuration Register 1 to a 1 enables conversions. It se-

quences through the three channels of V

, Internal

temperature sensor and External temperature sensor and

takes a measurement from each. At intervals of tbd ms

another measurement cycle is performed on all three chan-

nels. This method of taking a measurement on all three

channels in one cycle is called Round Robin. Setting Bit 4

of Control Configuration 2 (address 19h) disables the

Round Robin mode and in turn sets up the single channel

mode. The single channel mode is where only one chan-

nel, eg. Internal temperature sensor, is measured in each

conversion cycle.

The time taken to monitor all channels will normally not

be of interest, as the most recently measured value can be

read at any time.

For applications where the Round Robin time is impor-

tant, it can be easily calculated.

As mentioned previously a conversion on each temperature

channel takes 25 us and on the V

channel it takes 15 us.

Each channel is measured 16 times and internally aver-

aged to reduce noise.

The total cycle time for voltage and temperature channels

is therefore nominally :

(2 x 16 x 25) + (16 x 15) = 1.04 ms

SINGLE CHANNEL MEASUREMENT

Setting C4 of Control Configuration 2 register enables the

single channel mode and allows the ADT7316/17/18 to

focus on one channel only. A channel is selected by writ-

ing to Bits 0:2 in register Control Configuration 2 regis-

ter. For example, to select the V

channel for monitoring

write to the Control Configuration 2 register and set C4

to 1 (if not done so already), then write all 0

’

s to bits 0 to

2 . All subsequent conversions will be done on the V

channel only. To change the channel selection to the In-

ternal temperature channel, write to the Control Configu-

ration 2 register and set C0 = 1. When measuring in

single channel mode there is a time delay of TBD us be-

tween each measurement. A measurement is also initiated

after every read or write operation.
