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 VDD 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 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 = 200 ms, 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 TPS3307-18 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 TPS3307-18 includes an active-high RESET output.
The device is available in a standard 8-pin SO package, and is characterized for operation over a temperature
range of 40
°C to 125°C.
