MAX6457UKD3B+T Description

Short technical summary and product information.

The MAX6457UKD3B+T is a low-power voltage monitor IC designed for undervoltage or overvoltage detection. It operates across a wide supply voltage range of 4V to 28V and includes an internal 2.25V precision bandgap reference. The device features a single comparator with internal threshold hysteresis options and a high-voltage open-drain output that is 28V compliant.

 

This supervisor IC offers selectable timeout periods, including a 50μs typical delay for voltage detection and a 90ms minimum reset timeout delay for reset circuit applications. The output can be configured as active low. It is suitable for applications requiring precise voltage monitoring and protection, such as battery-stack powered equipment, notebooks, automotive, industrial, telecom, and networking systems.

 

The MAX6457UKD3B+T is available in a compact SOT-23-5 package, making it ideal for space-constrained designs. It is specified for operation over an extended temperature range of -40°C to +125°C (TA).
