Preliminary Technical Data
ADM1069
INPUTS
SUPPLY SUPERVISION
The ADM1069 has eight programmable inputs. Four of these
are dedicated supply fault detectors (SFDs). These dedicated
inputs are called VH and VP1–3 by default. The other four
inputs are labeled VX1–VX4 and have dual functionality. They
can be used as either supply fault detectors, with similar
functionality to VH and VP1–4, or CMOS/TTL-compatible
logic inputs to the devices. Therefore, the ADM1069 can have
up to ten analog inputs, a minimum of four analog inputs and
four digital inputs, or a combination. If an input is used as an
analog input, it cannot be used as a digital input. Therefore, a
configuration requiring ten analog inputs has no digital inputs
available.
Table 5 shows the details of each of the inputs.

PROGRAMMING THE SUPPLY FAULT DETECTORS
The ADM1069 has up to eight supply fault detectors (SFDs) on
its ten input channels. These highly programmable reset
generators enable the supervision of up to eight supply voltages.
The supplies can be as low as 0.573 V and as high as 14.4 V. The
inputs can be configured to detect an undervoltage fault (the
input voltage droops below a preprogrammed value), an
overvoltage fault (the input voltage rises above a
preprogrammed value) or an out-of-window fault
(undervoltage
or
overvoltage). The thresholds can be
programmed to an 8-bit resolution in registers provided in the
ADM1069. This translates to a voltage resolution that is
dependent on the range selected.
The resolution is given by
Step Size
=
Threshold Range
/255
Therefore, if the high range is selected on VH, the step size can
be calculated as follows:
(14.4 V 4.8 V)/255 = 37.6 mV
Table 4 lists the upper and lower limit of each available range,
the bottom of each range (V
B
), and the range itself (V
R
).

where:
V
T
is the desired threshold voltage (UV or OV).
V

is the voltage range.
N
is the decimal value of the 8-bit code.
V

is the bottom of the range.
Reversing the equation, the code for a desired threshold is given
by
N
= 255 × (

For example, if the user wants to set a 5 V OV threshold on VP1,
the code to be programmed in the PS1OVTH register
(discussed in the AN-698 application note) is given by
N
= 255 × (5 2.5)/3.5
Therefore,
N
= 182 (1011 0110 or 0xB6).
