Introduction  
• Precision supply-voltage monitor  
- 4.63V (PT7A7511, 7521, 7531)  
- 4.38V (PT7A7512, 7522, 7532)  
- 3.08V (PT7A7513, 7523, 7533)  
- 2.93V (PT7A7514, 7524, 7534)

• 200ms reset pulse width  
The PT7A751X/752X/753X family microprocessor  
(µP) supervisory circuits are targeted to improve  
reliability and accuracy of power-supply circuitry in  
µP 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-µp, power-  
down and brownout conditions for µP system;  
2. Detecting power failure or low-battery conditions  
with a 1.25V threshold detector;  
• Debounced TTL/CMOS-compatible manual-  
reset input  
• Independent watchdog timer 1.6sec time-out (not  
available for PT7A7531 - 7537)  
3. Watchdog functions (not for PT7A753x).  
• Reset output signal:  
- Active-low only (PT7A7511 - 7517)  
- Active-high only (PT7A7521 - 7527)  
- Active-high and active-low (PT7A7531 - 7537)  
Voltage monitor for power-fail or low battery warning  
• Guaranteed RESET/RESET valid at VCC = 1.2V  
Applications  
• Power-supply circuitry in µP systems
