function, manufactured using laser trimming

technology.

The series consist of a reference voltage source,

delay circuit, comparator, and output driver. With the

built-in delay circuit, the series do not require any

external components.

The

RESET

output is active LOW, when voltage below

DFL

is detected.

The EN (EN pin controls ON/OFF state of the

watchdog functions. This pin in an active state

disables the watchdog function, while the voltage

detector remains operational.

The IXD5122 and IXD5124 series have internal pull-

up/down resistors respectively that allows use these

IC with watchdog function active, while EN (EN pins

are left open.

The detect voltages are internally fixed in the range

from 1.6 V to 5.0 V in 0.1 V increments.

Six watchdog timeout periods are available in a range

from 50 ms to 1.6 s.

Five release delay times are available in a range from

3.13 ms to 400 ms.

With low power consumption and high accuracy, the

series is suitable for precision mobile equipment.

The IXD5121/22/23/24 in ultra small packages are

ideally suited for high-density PC boards.

The IXD5121/22/23/24 is available in N-channel open

drain output configuration only.

Detector is available in USP-6C and SOT-25

packages.

APPLICATIONS

Microprocessor reset circuitry

Memory battery back-up circuits

Power-on reset circuits

Power failure detection

System battery life and charge voltage monitors

DESCRIPTION

The IXD5121/22/23/24 are highly precise, low power

consumption, CMOS voltage detectors with watchdog
