LTC1326/LTC1326-2.5  
Micropower Precision  
Triple Supply Monitors

FEATURES  
DESCRIPTIO  
The LTC®1326/LTC1326-2.5 are triple supply monitors  
intended for systems with multiple supply voltages. They  
provide micropower operation, small size and high accu-  
racy supply monitoring.  
Simultaneously Monitors Three Supplies  
LTC1326: 5V, 3.3V and ADJ  
LTC1326-2.5: 2.5V, 3.3V and ADJ  
Guaranteed Threshold Accuracy: ±0.75%  
Low Supply Current: 20µA  
Tight 0.75% threshold accuracy and glitch immunity  
ensure reliable reset operation without false triggering.  
The 20µA typical supply current makes the LTC1326/  
LTC1326-2.5 ideal for power-conscious systems.  
Internal Reset Time Delay: 200ms  
Manual Push-Button Reset Input  
Active Low and Active High Reset Outputs  
Active Low “Soft” Reset Output  
The RST output is guaranteed to be in the correct state for  
CC3,VCC5orVCC25downto1V.TheLTC1326/LTC1326-2.5  
can be configured to monitor one, two or three inputs,  
depending on system requirements.  
Power Supply Glitch Immunity  
Guaranteed RESET for VCC3 1V or VCC5 1V  
or VCC25 1V  
V
8-Pin SO and MSOP Packages  
A manual push-button reset input provides the ability to  
generate a very narrow “soft” reset pulse (100µs typ) or a  
200ms reset pulse equivalent to a power-on reset. Both  
SRST and RST outputs are open-drain and can be OR-tied  
with other reset sources.
