SYSTEM RESET IC WITH DELAY CIRCUIT

■ GENERALDESCRIPTION

■ PACKAGE OUTLINE

The NJU7296 is a system reset IC with built-in delay circuit that

monitors the status of a power line, and outputs a reset signal to

the microcomputer.

The NJU7296 outputs a reset signal when fall below the detection

voltage.

NJU7296F1

Delay times are fixed internally and those are set in each of rising

and falling.

It is possible to monitor multiplex power line by combination of

NJU7296 because output voltage V_OUTis kept Low level when

EXTPin is Low level by connecting with other NJU7296.

Detection voltage’s default value is 1.0V. It can be adjusted to

desired voltage by the resistor divider.

In addition, a hysteresis voltage can be set arbitrarily by inserting a

resistor between the V_INpin and the HYS pin.

■ FEATURES

● High Precision Detection Voltage

● Detection Voltage

1.0% (Ta=25 C)

1.0V (default) and adjustable with external resistor

● Reset Output Logic

Reset Low output when V_INpin is detection voltage or below

*If required reset low output when V_INpin is detection voltage or more, see the

NJU7295.

● Delay Circuit (Internal Fixed type) Rising / Falling independent setting

● Ultra Low Quiescent Current

● Supply Voltage Range

● External Input pin

1.7µAtyp.

1.5 to 5.5V

While inputting low signal, keep output Low level

●Adjustable Hysteresis Voltage

● OutputType

● Package
