MAX809LEUR-T Description

Short technical summary and product information.

The MAX809LEUR-T is a microprocessor supervisory circuit from Analog Devices, designed for reliable power supply monitoring in digital systems. It features a single voltage monitoring channel with a reset threshold of 4.63V and an active-low reset output.

 

This device asserts a reset signal when the VCC supply voltage drops below the preset threshold, maintaining the reset for at least 140ms after VCC has risen above the threshold. The output is push-pull with a totem pole configuration. It operates over a temperature range of -40°C to 85°C (TA).

 

The MAX809LEUR-T is available in a surface mount SOT-23-3 package, also described as TO-236-3 or SC-59. This compact package is suitable for space-constrained applications. The component is designed to eliminate external components and adjustments when used with common power supply voltages.
