The actual sense voltage has to be adjusted by an external resistor divider according to the application requirements.

During power-on, RESET is asserted when the supply voltage V
DD
becomes higher than 1.1 V. Thereafter, the
supply voltage supervisor monitors the SENSEn inputs
and keeps RESET active as long as SENSEn
remain
below the threshold voltage V
IT+
.
An internal timer delays the return of the RESET output to the inactive state (high) to ensure proper system reset.
The delay time, t
d typ
= 200 ms, starts after all SENSEn inputs
have risen above the threshold voltage V
IT+
. When
the voltage at any SENSE input drops below the threshold voltage V
IT–
, 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.
