description (continued)
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
OUT
and keeps the RESET output active as long as V
OUT
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
OUT
has risen above V
IT
. When the supply
voltage drops below V
IT
, the output becomes active (low) again.
The TPS3606-33 is available in a 10-pin MSOP package and is characterized for operation over a temperature
range of −40_C to 85_C.
