LTC1727/LTC1728

Micropower Precision

Triple Supply Monitors

in 8-Lead MSOP and

5-Lead SOT-23 Packages

FEATURES

DESCRIPTIO

The LTC^®1727 is a triple supply monitor intended for

systemswithmultiplesupplyvoltages. Eachsupplymoni-

tor has its own open-drain output for individual supply

monitoring. A common open-drain reset output remains

low until all three supplies have been in compliance for

200ms. Tight 1.5% accuracy specifications and glitch

immunity ensure reliable reset operation without false

triggering.

■

Monitors Three Inputs Simultaneously

LTC1727-5: 5V, 3.3V and ADJ

LTC1727-2.5: 2.5V, 3.3V and ADJ

LTC1728-5: 5V, 3.3V and ADJ

LTC1728-2.5: 2.5V, 3.3V and ADJ

LTC1728-1.8: 3V, 1.8V and ADJ

■

±1.5% Threshold Accuracy Over Temperature

■

Very Low Supply Current: 10µA Typ

■

200ms Reset Time Delay

Active Low RESET Output

The LTC1728 is functionally identical to the LTC1727

without the individual monitor outputs.

■

Power Supply Glitch Immunity

■

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

_CC5/V_CC25/V_CC18or V_CC3down to 1V. The LTC1727/

LTC1728 may also be configured to monitor any one or

two V_CCinputs instead of three, depending on system

requirements.

Guaranteed RESET for V_CC3≥ 1V

or V_CC5/V_CC25/V_CC18≥ 1V

■

LTC1727 Includes Monitor Output for Each Supply

LTC1727: 8-Lead MSOP and SO Packages

LTC1728: 5-Lead SOT-23 Package

APPLICATIO S

■

The LTC1727 is available in an 8-lead MSOP or SO

package and the LTC1728 is available in a 5-lead SOT-23
