Typical Application
ispPAC-POWR1014 integrates many traditional discrete ICs, which are used to start up a microprocessor with a CPU_RESET, to monitor for over and under voltage and monitor the health of the of the software execution though a watchdog timer. In addition the POWR1014 also integrates power supply sequencing and positive voltage hot-swap control. Varied functionality requirements of each circuit board can be met through programming.
