Features  
Discription  
• Precision supply-voltage monitor  
- 4.63V (PT7A7511, 7521, 7531)  
- 4.38V (PT7A7512, 7522, 7532)  
- 3.08V (PT7A7513, 7523, 7533)  
- 2.93V (PT7A7514, 7524, 7534)  
- 2.63V (PT7A7515, 7525, 7535)  
The PT7A751X/752X/753X family microprocessor (µP)  
supervisory circuits are targeted to improve reliability and  
accuracy of power-supply circuitry in µP’s systems.  
These devices reduce the complexity and number of  
components required to monitor power-supply and battery  
functions.  
• 200ms reset pulse width  
The main functions are:  
• Debounced TTL/CMOS-compatible manual-  
reset input  
1. Asserting reset output during power-up, power-down  
and brownout conditions for µP system;  
2. Detecting power failure or low-battery conditions with  
a 1.25V threshold detector;  
• Independent watchdog timer 1.6sec time-out (not  
available for PT7A7531 - 7535)  
• Reset output signal:  
3. Watchdog functions (not for PT7A753x).  
- Active-low only (PT7A7511 - 7515)  
- Active-high only (PT7A7521 - 7525)  
- Active-high and active-low (PT7A7531 - 7535)  
Voltage monitor for power-fail or low battery warning  
• Guaranteed RESET/RESET valid at VCC = 1.2V  
Applications  
• Power-supply circuitry in µP systems
