TPS3619-33DGK General Description

The 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, RESET is asserted when the supply voltage (V_DD or V_BAT) becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors V_DD and keeps RESET output active as long as V_DD remains below the threshold voltage (V_IT). An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time starts after V_DD has risen above V_IT. When the supply voltage drops below V_IT, 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.
