TPS3705-33DR

The TPS370x-xx family of microprocessor supplyvoltage supervisors provide circuit initialization and
timing supervision, primarily for DSP and processorbased systems.
During power-on, RESET is asserted when the supply
voltage V DD becomes higher than 1.1 V. Thereafter,
the supply voltage supervisor monitors VDD and keeps
RESET active as long as V DD remains below the
threshold voltage VIT+. When the supply voltage drops
below the threshold voltage VIT–, the output becomes
active (low) again. No external components are
required. All the devices of this family have a fixedsense threshold voltage VIT– set by an internal voltage
divider.
The product spectrum is designed for supply voltages
of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available
in either 8-pin MSOP or standard SOIC packages.
The TPS370x-xx devices are characterized for
operation over a temperature range of −40°C to 85°C.
