MAX809MEUR-T Description

Short technical summary and product information.

The MAX809MEUR-T is a microprocessor supervisory circuit designed to monitor a single voltage rail. It asserts a reset signal when the supply voltage drops below the 4.38V threshold and maintains reset for a minimum of 140ms after the voltage returns above the threshold.

The device features an active-low, push-pull output, making it suitable for directly driving the reset input of microcontrollers and other logic devices. It operates over a temperature range of -40°C to +105°C.

Housed in a compact SOT-23-3 surface-mount package, the MAX809MEUR-T is ideal for space-constrained applications requiring reliable power-on reset and brown-out protection.
