MIC2775

Micro-Power Voltage Supervisor

Advance Information

General Description

Features

The MIC2775 is a power supply supervisor that provides

under-voltagemonitoring,manualresetcapability,andpower-

on reset generation in a compact 5-pin SOT package. Fea-

tures include an under-voltage detector, a delay generator, a

manual reset input, and both active-high and active-low reset

• Monitors power supply for under-voltage conditions

• Choice of factory-programmed thresholds

• Generates 140ms (minimum) power-on RESET pulse

• Manual reset capability

• Both active-high and active-low RESET outputs

• /RST output valid down to 1.2V

outputs. The under-voltage detector compares V against

a fixed threshold. Ten factory-programmed thresholds are

available.

• Ultra-low supply current, 3.5µA typical

• Rejects brief input transients

• No external components

• Pin compatible upgrade for MAX825

• IttyBitty™ 5-lead SOT-23 package

The reset outputs are asserted for no less than 140ms at

power-on and any time the input voltage drops below the

reference voltage. It remains asserted for the timeout period

after the input voltage subsequently rises back above the

threshold boundary. A reset can be generated at any time by

asserting the manual reset input, /MR. This reset output will

remain active at least 140ms after the release of /MR. The

/MR input can also be used to daisy-chain the MIC2775 onto

existing power monitoring circuitry or other supervisors.

Hysteresis is included to prevent chattering due to noise.

Typical supply current is a low 3.5µA.

Applications

• Monitoring processor core and input/output voltages

• Computer systems

• PDAs, hand-held PCs

• Embedded controllers

• Telecommunications systems

• Power supplies
