(1) 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.
APPLICATIONS
• Applications Using Low-Power DSPs,
Microcontrollers, or Microprocessors
• Portable- and Battery-Powered Equipment
• Intelligent Instruments
• Wireless Communication Systems
• Industrial Equipment
• Notebook/Desktop Computers
DESCRIPTION
The TPS310x and TPS311x families of supervisory
circuits provide circuit initialization and timing
supervision, primarily for DSP and processor-based
systems.
During power-on, RESET is asserted when the
supply voltage (V_DD) becomes higher than 0.4 V.
Thereafter, the supervisory circuit monitors V_DD and
keeps the RESET output active as long as V_DD
remains below the threshold voltage (V_IT). An internal
timer delays the return of the output to the inactive
state to ensure proper system reset. The delay time
starts after V_DD has risen above V_IT. When V_DD drops
below V_IT, the output becomes active again.
All the devices of this family have a fixed-sense
threshold voltage (V_IT) set by an internal voltage
divider.
The TPS3103 and TPS3106 have an active-low,
open-drain RESET output. The TPS3110 has an
active-low push/pull RESET.
The product spectrum is designed for supply
voltages of 0.9 V up to 3.3 V. The circuits are
available in SOT23-6 packages. The TPS31xx family
is characterized for operation over a temperature
range of –55°C to 125°C.
