ispPAC-POWR1208 Data Sheet
Power Supply Sequence Controller and Monitor
The ispPAC-POWR1208 device is speci?cally designed as a fully-programmable power supply sequencing control-
ler and monitor for managing up to eight separate power supplies, as well as monitoring up to 12 analog inputs or
supplies. The ispPAC-POWR1208 device contains an internal PLD that is programmable by the user to implement
digital logic functions and control state machines. The internal PLD connects to four programmable timers, special
purpose I/O and the programmable monitoring circuit blocks. The internal PLD and timers can be clocked by either
an internal programmable clock oscillator or an external clock source.
The voltage monitors are arranged as 12 independent comparators each with 192 programmable trip point set-
tings. Monitoring levels are set around the following standard voltages: 1.2V, 1.5V, 1.8V, 2.5V, 3.3V or 5.0V.
All 12 voltages can be monitored simultaneously (i.e., continuous-time operation). Other non-standard voltage lev-
els can be accounted for using various scale factors.
For added robustness, the comparators feature a variable hysteresis that scales with the voltage they monitor.
Generally, a larger hysteresis is better. However, as power supply voltages get smaller, that hysteresis increasingly
affects trip-point accuracy. Therefore, the hysteresis is +/-16mV for 5V supplies and scales down to +/-3mV for 1.2V
supplies, or about 0.3% of the trip point.
The programmable logic functions consist of a block of 36 inputs with 81 product terms and 16 macrocells. The
architecture supports the sharing of product terms to enhance the overall usability.
Output pins are con?gurable in two different modes. There are eight outputs for controlling eight different power
supplies. OUT5-OUT8 are open-drain outputs for interfacing to other circuits. The HVOUT1-HVOUT4 pins can be
programmed individually as open-drain outputs or as high voltage FET gate drivers. As high voltage FET gate
driver outputs, they can be used to drive an external N-Channel MOSFET as a switch to control the voltage ramp-
up of the target board. The four HVOUT drivers have programmable current and voltage levels. Of the eight out-
puts, four can be con?gured in the FET gate driver mode or open-drain digital mode.
