Product details

Low-power 555 timer for battery and industrial designs

The Maxim ICM7555ESA+T is a CMOS 555-type timer/oscillator that drops the supply current to 30 µA — roughly 1/100th of the classic bipolar NE555 — while keeping the same pinout and basic function. It oscillates up to 500 kHz and runs from a 2V to 16.5V supply, so it fits both 3.3V portable gear and legacy 12V industrial panels.

The 30 µA quiescent current is the headline spec that separates this part from a standard 555. In a battery-powered timer or watchdog circuit, that difference can extend standby life from weeks to years on a coin cell. The 500 kHz maximum frequency is adequate for PWM dimming, tone generation, and one-shot delays up to several seconds; for higher-speed clocking you would step to a dedicated oscillator.

Pin-compatible with the standard 555 footprint

The ICM7555ESA+T is housed in an 8-SOIC package (3.90 mm body width) and is a drop-in replacement for any 8-pin 555-type timer on the same footprint.

Frequently asked questions

Is ICM7555ESA+T a direct replacement for ICM7555ESA?

Yes, the ICM7555ESA+T is electrically identical to the ICM7555ESA; the T suffix only denotes Tape & Reel packaging. It is a direct drop-in replacement.

Is ICM7555ESA+T RoHS compliant?

Yes, the ICM7555ESA+T is ROHS3 compliant.

What is the difference between ICM7555ESA+T and LMC555?

Both are CMOS 555 timers with similar low supply current. The ICM7555ESA+T is specified for a 2V to 16.5V supply range and 500 kHz maximum frequency; the LMC555 typically operates from 1.5V to 15V and reaches 3 MHz. The choice depends on your voltage floor and timing speed requirements.
