1.All possible comparator trip voltages using internal attenuation settings.
Table 1-1 shows all possible comparator trip point voltage settings. The internal resistive divider allows ranges for
1.2V, 1.8V, 2.5V, 3.3V and 5.0V. There are 192 available voltages, ranging from 1.036V to 5.723V. In addition to the
192 voltage monitor trip points, the user can add additional resistors outside the device to divide down the voltage
and achieve virtually any voltage trip point. This allows the capability to monitor higher voltages such and 12V, 15V,
24V, etc. Voltage monitor trip points are set in the graphical user interface of PAC-Designer software by simple pull-
down menus. The user simply selects the given range and corresponding trip point value. Attenuation and refer-
ence values are set internally using E 2 CMOS con?guration bits internal to the device.
Figure 1-2 shows a single comparator, the attenuation network and reference used to program the monitor trip
points. Each of the twelve comparators are independently set in the same way.
Theory Of Operation
The ispPAC-POWR1208 incorporates programmable voltage monitors along with digital inputs and outputs as well
as high voltage FET gate drivers to control MOSFETs for ramping up power supply rails. The 16 macrocell PLD
inputs are from the 12 voltage monitors and four digital inputs. There are four embedded programmable timers that
interface with the PLD, along with an internal programmable oscillator.
The 12 independently programmable voltage monitors each have 192 programmable trip points.
Figure 1-2 shows a simpli?ed schematic representation of one of these monitors.
