General Description

The series are designed to monitor power supplies in µP

and

digital

systems.

It

provides

excellent

circuit

reliability

and

low

cost

by

eliminating

external

components and adjustments, and a debounced manual

reset input.

This device performs a single function: it asserts a reset

preset threshold or whenever manual reset is asserted.

Reset remains asserted for an internally programmed

the reset threshold or manual reset is de-asserted.

PT7M6314USxx are bidirectional output, allowing it to

be directly connected to µP with bidirectional reset inputs.

The serials come with factory-trimmed reset threshold

voltages in 100mV increments from 2.5V to 5V. Preset

timeout periods of 200ms and 1570ms (typ.) are available.
