BACKUP-BATTERY SUPERVISORS FOR RAM RETENTION
2
Supply Current of 40 A (Max)
Battery-Supply Current of 100 nA (Max)
The TPS3619 and TPS3620 families of supervisory
circuits monitor and control processor activity by
Precision Supply Voltage Monitor 3.3 V, 5 V,
providing backup-battery switchover for data retention
Other Options on Request
of CMOS RAM.
Backup-Battery Voltage Can Exceed V
DD
During power on, RESET is asserted when the
Power On Reset Generator With Fixed 100-ms
supply voltage (VDD or VBAT) becomes higher than 1.1
Reset Delay Time
V. Thereafter, the supply voltage supervisor monitors
Voltage Monitor For Power-Fail or Low-Battery
VDD and keeps RESET output active as long as VDD
Monitoring
remains below the threshold voltage (VIT). An internal
timer delays the return of the output to the inactive
Battery Freshness Seal (TPS3619)
state (high) to ensure proper system reset. The delay
Pin-For-Pin Compatible With MAX819,
time starts after VDD has risen above VIT. When the
MAX703, and MAX704
supply voltage drops below VIT, the output becomes
8-Pin MSOP Package
active (low) again.
Temperature Range –40°C to +85°C
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
Fax Machines
of –40
°C to +85°C.
