General Description
The series are designed to monitor power supplies in µ
P
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
signal whenever the V
CC
supply voltage falls below a
preset threshold or whenever manual reset is asserted.
Reset remains asserted for an internally programmed
interval (reset timeout period) after V
CC
has risen above
the reset threshold or manual reset is deasserted.
PT7M6314USxx are bidirectional output, allowing it to
be directly connected to µ with bidirectional reset inputs.
P
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.

Description
Reset Output and Pushbutton Input:
RST is asserted when V

. Active
low. When other devices pull RST low, the device will speed its rising edge once the reset condition release.
Manual Reset:
A logic low on MR asserts reset. Reset remains asserted as long as MR is low, and for the
reset timeout period (t
RS
) after the reset conditions are terminated. Connect to V
