Product details

What this reset IC does and where it fits

The Analog Devices MAX6464XR44+T is a simple reset/power-on reset IC that monitors a single supply rail and holds the reset output active low until the supply has been above the 4.4 V threshold for at least 150 ms. The push-pull output eliminates the need for an external pull-up resistor, which simplifies the BOM on space-constrained boards. This part is designed for systems that need a clean, glitch-free startup sequence — think MCU-based controllers, automotive ECUs, or industrial sensor nodes where the processor must not begin executing until the supply is stable.

Threshold and timeout — what they mean for your design

The 4.4 V threshold is the voltage at which the reset asserts. The 150 ms minimum reset timeout gives the power supply and oscillator time to settle.

Lifecycle and compliance — no obsolescence risk

Frequently asked questions

What are the alternatives to MAX6464XR44+T?

Pin-compatible alternatives exist within the same family of simple reset ICs from Analog Devices and other manufacturers that share the SC-70-3 footprint and active-low push-pull output. The key selection parameter is the threshold voltage — this part monitors a 4.4 V rail, so an alternative must match that threshold or be acceptable for your supply voltage.
