J a u ! l p a ~ n 8 l e l 0 0 N N L TMS320LF2402PZS Price The LTC~1644 is a Hot Swap" controllerthat allows a board to be safely inserted and removed from a CompactPCI bus slot. External N-channel transistors control the 3.3V/5V supplies, while on-chip switches control the -12V and 12V supplies. The 3.3V and 5V supplies can be ramped up at a prog rammable rate. Electronic circuit break- ers protect all four supplies against ove rcurrent faults. The PWRGD outputindicates when all ofthe supply voltages are within tole rance. The OFF/ON pin is used to cycle the board power or reset the circuit breaker. The PRECHARGE output can be used to bias the bus l/0 pins during card insertion and extraction. PCI_RST# is combined on-chip with HEALTHY# in order to generate LOCAL_PCI_RST#. TMS320LF2402PZS on stock The alarm can be programmed to activate on a specific day of the month or repeat every day, hour, minute, or second. It can also be programmed to go off while the DS1554 is in the battery backed state of operation to serve as a system wake-up. Alarm mask bits AMl-AM4 control the alarm mode. Table 3 shows the possible settings. Configurations not listed in the table default to the once per second mode to notify the user of an incorrect alarm setting.
