Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

The TPS3307-xx family is a series of micropower supply voltage supervisors designed for circuit initialization primarily in DSP and processor-based systems which require more than one supply voltage.

The TPS3307-18 and TPS3307-33 are designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj and 5V/3.3V/adj, respectively. The adjustable SENSE input allows the monitoring of any supply voltage >1.25 V.

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, tdtyp = 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-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 a standard 8-pin SO packages and are characterized for operation over a temperature range of -55°C to 125°C.
