LTC1326/LTC1326-2.5

Micropower Precision

Triple Supply Monitors

FEATURES

DESCRIPTIO

The LTC^®1326/LTC1326-2.5 are triple supply monitors

intended for systems with multiple supply voltages. They

provide micropower operation, small size and high accu-

racy supply monitoring.

■

Simultaneously Monitors Three Supplies

LTC1326: 5V, 3.3V and ADJ

LTC1326-2.5: 2.5V, 3.3V and ADJ

■

Guaranteed Threshold Accuracy: ±0.75%

■

Low Supply Current: 20µA

Tight 0.75% threshold accuracy and glitch immunity

ensure reliable reset operation without false triggering.

The 20µA typical supply current makes the LTC1326/

LTC1326-2.5 ideal for power-conscious systems.

■

Internal Reset Time Delay: 200ms

■

Manual Push-Button Reset Input

■

Active Low and Active High Reset Outputs

■

Active Low “Soft” Reset Output

■

The RST output is guaranteed to be in the correct state for

_CC3,V_CC5orV_CC25downto1V.TheLTC1326/LTC1326-2.5

can be configured to monitor one, two or three inputs,

depending on system requirements.

Power Supply Glitch Immunity

Guaranteed RESET for V_CC3≥ 1V or V_CC5≥ 1V

or V_CC25≥ 1V

■

8-Pin SO and MSOP Packages

A manual push-button reset input provides the ability to

generate a very narrow “soft” reset pulse (100µs typ) or a

200ms reset pulse equivalent to a power-on reset. Both

SRST and RST outputs are open-drain and can be OR-tied

with other reset sources.
