Texas Instruments TPS3620-33DGKTThe TPS3619 and TPS3620 families of supervisory circuits monitor and control processor activity by providing backup-battery switchover for data retention of CMOS RAM.
During power on,RESETis asserted when the supply voltage (VDDor VBAT) becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VDDand keepsRESEToutput active as long as VDDremains 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 VDDhas risen above VIT. When the supply voltage drops below VIT,the output becomes active (low) again.
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.
