description
The TPS3610 family of supervisory circuits monitors and controls processor activity by providing backup-battery
switchover for data retention of CMOS RAM. Other features include an additional power-fail comparator,
low-line indication, watchdog function, battery-status indicator, manual switchover, and write protection for
CMOS RAM.
The TPS3610 family allow usage of 3-V or 3.6-V lithium batteries as the backup supply in systems with, e.g.,
VDD = 1.8 V. 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 the threshold voltage VIT.
When the supply voltage drops below the threshold voltage VIT, the output becomes active (low) again.
The product spectrum is designed for supply voltages of 1.8 V and 5 V. The circuits are available in a 14-pin
TSSOP package. TPS3610 devices are characterized for operation over a temperature range of –40
°C to 85°C.
