BACKUP-BATTERY SUPERVISORS FOR RAM RETENTION  
FEATURES  
DESCRIPTION  
•
•
•
Supply Current of 40 µA (Max)  
The TPS3619 and TPS3620 families of supervisory  
circuits monitor and control processor activity by  
providing backup-battery switchover for data retention  
of CMOS RAM.  
Battery-Supply Current of 100 nA (Max)  
Precision Supply Voltage Monitor 3.3 V, 5 V,  
Other Options on Request  
During power on, RESET is asserted when the  
supply voltage (VDD or VBAT) becomes higher than 1.1  
V. Thereafter, the supply voltage supervisor monitors  
VDD and keeps RESET output active as long as VDD  
remains below the threshold voltage (VIT). An internal  
timer delays the return of the output to the inactive  
state (high) to ensure proper system reset. The delay  
time starts after VDD has risen above VIT. When the  
supply voltage drops below VIT, the output becomes  
active (low) again.  
•
•
Backup-Battery Voltage Can Exceed VDD  
Power On Reset Generator With Fixed 100-ms  
Reset Delay Time  
•
Voltage Monitor For Power-Fail or  
Low-Battery Monitoring  
•
•
Battery Freshness Seal (TPS3619)  
Pin-For-Pin Compatible With MAX819,  
MAX703, and MAX704  
•
•
8-Pin MSOP Package  
The product spectrum is designed for supply voltages  
of 3.3 V and 5 V. The TPS3619 and TPS3620 are  
available in an 8-pin MSOP package and are  
characterized for operation over a temperature range  
of -40°C to 85°C.  
Temperature Range -40°C to 85°C
