The TPS370x-xx family of microprocessor supply-voltage supervisors provide circuit
initialization and timing supervision, primarily for DSP and processor-based systems.
During power-on, RESET is asserted when the supply voltage
VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor
monitors VDD and keeps RESET active as long as
VDD 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 fixed-sense threshold voltage VIT– set by an internal voltage
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.
