2V Description The PT7A751X/752X/753X family microprocessor (P) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in P’s systems.
These devices reduce the complexity and number of components required to monitor power-supply and battery functions.
The main functions are: 1.
Asserting reset output during power-up, power- down and brownout conditions for P system.
2.
Detecting power failure or low-battery conditions with a 1.
25V threshold detector.
3.
Watchdog functions (not for PT7A753x) Applications  Power-supply circuitry in P systems PT7A7511P-7515P Pin ConfPiTg7uAr7a51ti1oWn-7515W 8-Pin PDIP/8-Pin SOIC PT7A7521P-7525P PT7A7521W-7525W 8-Pin PDIP/8-Pin SOIC PT7A7531P-7535P PT7A7531W-7535W 8-Pin PDIP/8-Pin SOIC MR V CC GND PFI 1 2 3 4 8 WDO MR 1 7 RESET V CC 2 6 WDI GND 3 5 PFO PFI 4 8 WDO MR 1 7 R...
