DESCRIPTION
Pin-to-Pin Compatible With MAX819, MAX703,
The TPS3619 and TPS3620 families of supervisory
and MAX704
circuits monitor and control processor activity by
8-Pin Mini Small-Outline Package (MSOP)
providing backup-battery switchover for data retention
Package
of CMOS RAM.
During power on, RESET is asserted when the
SUPPORTS DEFENSE, AEROSPACE,
supply voltage (VDD or VBAT) becomes higher than 1.1
AND MEDICAL APPLICATIONS
V. Thereafter, the supply voltage supervisor monitors
Controlled Baseline
VDD and keeps RESET output active as long as VDD
One Assembly/Test Site
remains below the threshold voltage (VIT). An internal
One Fabrication Site
timer delays the return of the output to the inactive
state (high) to ensure proper system reset. The delay
Available in Military (–55°C/125°C)
time starts after VDD has risen above VIT. When the
Temperature Range(1)
supply voltage drops below VIT, the output becomes
Extended Product Life Cycle
active (low) again.
Extended Product-Change Notification
The product spectrum is designed for supply voltages
Product Traceability
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

Additional temperature ranges available - contact factory
of –55°C to 125°C.
