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.  
♦ Low +1.2V Operating Supply Voltage (V or V  
♦ Precision Monitoring of +5.0V, +3.3V, +3.0V, and  
+2.5V Power-Supply Voltages  
)
CC  
BATT  
♦ On-Board Gating of Chip-Enable Signals, 1.5ns  
Propagation Delay  
♦ Debounced Manual Reset Input (MAX6365)  
♦ Watchdog Timer, 1.6s Timeout (MAX6366)  
♦ Battery-On Output Indicator (MAX6367)  
♦ Auxiliary User-Adjustable RESET IN (MAX6368)  
♦ Low 10µA Quiescent Supply Current  
♦ 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.  
♦ 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  
or V  
)
CC  
BATT  
♦ Power-Supply Transient Immunity  
♦ 150ms min Reset Timeout Period  
♦ 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 the 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 the Selector  
Guide). The MAX6365–MAX6368 are available in minia-  
ture 8-pin SOT23 packages.

*These parts offer a choice of reset threshold voltages. From the  
Reset Threshold Ranges table, insert the desired threshold volt-  
age code in the blank to complete the part number. SOT parts  
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  
Selector Guide for a listing of device features.
