SOT23, Low-Power µP Supervisory Circuits  
with Battery Backup and Chip-Enable Gating  
General Description  
Features  
The MAX6365–MAX6368 supervisory circuits simplify  
power-supply monitoring, battery-backup control func-  
tions, and memory write protection in microprocessor  
(µP) systems. The circuits significantly improve the size,  
accuracy, and reliability of modern systems with an ultra-  
small integrated solution.  
o Low +1.2V Operating Supply Voltage (V or V  
o Precision Monitoring of +5.0V, +3.3V, +3.0V, and  
+2.5V Power-Supply Voltages  
)
CC  
BATT  
o On-Board Gating of Chip-Enable Signals, 1.5ns  
Propagation Delay  
o Debounced Manual Reset Input (MAX6365)  
o Watchdog Timer, 1.6s Timeout (MAX6366)  
o Battery-On Output Indicator (MAX6367)  
o Auxiliary User-Adjustable RESET IN (MAX6368)  
o Low 10µA Quiescent Supply Current  
o Three Available Output Structures  
These devices perform four basic system functions:  
1) Provide a µP reset output during V  
supply power-  
CC  
up, power-down, and brownout conditions.  
2) Internally control V to backup-battery switching to  
CC  
maintain data or low-power operation for CMOS  
RAM, CMOS µPs, real-time clocks, and other digital  
logic when the main supply fails.  
Push-Pull RESET  
Open-Drain RESET  
Open-Drain RESET  
3) Provide memory write protection through internal  
chip-enable gating during supply or processor faults.  
o RESET/RESET Valid Down to 1.2V Guaranteed  
4) Include one of the following options: a manual reset  
input (MAX6365), a watchdog timer function  
(MAX6366), a battery-on output (MAX6367), or an  
auxiliary user-adjustable reset input (MAX6368).  
(V  
CC  
or V  
)
BATT  
o Power-Supply Transient Immunity  
o 150ms min Reset Timeout Period  
o Miniature 8-Pin SOT23 Package  
The MAX6365–MAX6368 operate from V  
supply volt-  
CC  
ages as low as 1.2V. The factory preset reset threshold  
voltages range from 2.32V to 4.63V (see Ordering  
Information). In addition, each part is offered in three  
reset output versions: push-pull active low, open-drain  
active low, or open-drain active high (see Selector  
Guide). The MAX6365–MAX6368 are available in minia-  
ture 8-pin SOT23 packages.

come in tape-and-reel only and must be ordered in 2500-piece  
increments. See Device Marking Codes for a complete parts list,  
including SOT top marks and standard threshold versions. See
