3 Description

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 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 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.
