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.

description
The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in
automotive DSP and processor-based systems, which require more than one supply voltage.
The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable
SENSE input allows the monitoring of any supply voltage >1.25 V.
