The TPS3613-01 supervisory circuit monitors  
MR  
and controls processor activity by providing  
backup-battery switchover for data retention of  
CMOS RAM.

During power on, RESET is asserted when the supply voltage (V  
or V  
) becomes higher than 1.1 V.

Thereafter, the supply voltage supervisor monitors V  
and keeps RESET output active as long as V  
remains

below the threshold voltage V . 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  
has risen above the threshold voltage V .

When the supply voltage drops below the threshold voltage V , the output becomes active (low) again.

The TPS3613-01 is available in a 10-pin MSOP package and is characterized for operation over a temperature  
range of –40°C to 85°C.
