Function/Truth Tables
SLVS199C – DECEMBER 1998 – REVISED DECEMBER 2006
During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1V. Thereafter, the
supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain
below the threshold voltage VIT+.
An internal timer delays the return of the RESET output to the inactive state (high) to ensure proper system
reset. The delay time, td (typ) = 200ms, starts after all SENSEn inputs have risen above the threshold voltage VIT+.
When the voltage at any SENSE input drops below the threshold voltage VIT–, the RESET output becomes
active (low) again.
The TPS3307-xx family of devices incorporates a manual reset input, MR. A low level at MR causes RESET to
become active. In addition to the active-low RESET output, the TPS3307-xx family includes an active-high
RESET output.
The devices are available in either 8-pin MSOP or standard 8-pin SO packages.
The TPS3307-xx devices are characterized for operation over a temperature range of –40
°C to +85°C.
