Maxim Integrated 1 Voltage Supervisor Microprocessor Supervisory Circuit 8-Pin SOT-23 MAX6371KA+T

Maxim Integrated MAX6371KA+T Voltage Supervisor is a precision microprocessor supervisory circuit designed to ensure reliable operation for critical microprocessor and microcontroller applications. It integrates a watchdog timer to monitor system activity, featuring pin-selectable watchdog timeout and startup delay periods, allowing customization without the need for power cycling.

This device operates efficiently with a low supply current of 8µA over a voltage range of 2.5V to 5.5V, making it ideal for power-sensitive embedded control systems. It provides flexible output driver options including open-drain and push-pull active-low watchdog outputs.

Built in a compact 8-pin SOT-23 surface mount package with dimensions of 3mm length, 1.75mm width, and 1.3mm height, the MAX6371KA+T is suited for automated assembly in space-constrained designs. The device is qualified to the automotive AEC-Q100 standard and supports operation in extreme temperature conditions from -40°C to 125°C, making it suitable for automotive, industrial controllers, telecommunications, and networking applications.

The MAX6371KA+T requires no external components, simplifying design and reducing bill of materials cost. Its watchdog disable feature offers additional flexibility for embedded systems where watchdog timing adjustments are necessary. This device helps prevent microprocessor lock-up and power failure events, thus enhancing system reliability and safety.
