AP1701/2/3/4  
3-Pin Microprocessor Reset Circuits  
„ Features  
„ General Description  
- Precision Monitoring of +2.5V, +3V, +3.3V, and  
+5V  
The AP1701/2/3/4 are used for microprocessor (µP)  
supervisory circuits to monitor the power supplies in  
µP and digital systems. They provide excellent  
circuit reliability and low cost by eliminating external  
components and adjustments when used with +5V,  
+3.3V, +3.0V powered circuits.  
Power-Supply Voltages  
- Fully Specified Over Temperature  
- Available in Three Output Configurations  
- Push-Pull RESET Low Output (AP1701/3)  
- Push-Pull RESET High Output (AP1702/4)  
- 200ms min Power-On Reset Pulse Width  
- 20µA Supply Current (Typ.)  
These circuits perform a single function: they assert  
a reset signal whenever the VCC supply voltage  
declines below a preset threshold, keeping it  
asserted for at least 240ms after VCC has risen  
above the reset threshold. Reset thresholds  
suitable for operation with a variety of supply  
voltages are available. The AP1701/2/3/4 have  
push pull outputs. The AP1701/3 have an active low  
RESET output, while the AP1702/4 has an active  
high RESET output. The reset comparator is  
designed to ignore fast transients on VCC, and the  
outputs are guaranteed to be in the correct logic  
state for VCC down to 1V. Low supply current  
makes the AP1701/2/3/4 ideal for use in portable  
equipment. The AP1701/2/3/4 is available in a 3-pin  
SOT23,TSOT23 package.  
- Guaranteed Reset Valid to VCC = +1V  
- Power Supply Transient Immunity  
- No External Components  
- 3-pin SOT23, TSOT23, Pb-Free Package  
„ Applications  
- Computers  
- Controllers  
- Intelligent Instruments  
- Critical µP and µC Power Monitoring  
- Portable/Battery Powered Equipment  
- Automotive
