MOSFET drivers. In high-voltage mode these outputs can provide up to 12V for driving the gates of n-channel
MOSFETs so that they can be used as high-side power switches controlling the supplies with a programmable
ramp rate for both ramp up and ramp down.
The ispPAC-POWR1014/A incorporates a 24-macrocell CPLD that can be used to implement complex state
machine sequencing for the control of multiple power supplies as well as combinatorial logic functions. The status
of all of the comparators on the analog input channels as well as the general purpose digital inputs are used as
inputs by the CPLD array, and all digital outputs may be controlled by the CPLD. Four independently programmable
timers can create delays and time-outs ranging from 32µs to 2 seconds. The CPLD is programmed using Logi-
Builder™, an easy-to-learn language integrated into the PAC-Designer
monitor the status of any of the analog input channel comparators or the digital inputs.
The on-chip 10-bit A/D converter is used to monitor the V
ispPAC-POWR1014A device.

during manufacturing.
