Maxim Integrated Voltage Supervisor 1 Supervisor Watchdog Timer 8-Pin SOT-23 MAX6374KA+T

Maxim Integrated MAX6374KA+T is a voltage supervisor designed for precision monitoring of critical microprocessor (μP) and microcontroller (μC) applications. It features a single supervisory circuit combined with a watchdog timer, which enhances reliability in embedded control systems, industrial controllers, networking, and telecommunications.

This voltage supervisor operates over a supply voltage range of +2.5V to +5.5V, consuming a low supply current of 8μA, making it highly efficient for battery-powered and low-power applications. It includes pin-selectable watchdog timeout periods and startup delay periods which can be changed without requiring power cycling, allowing dynamic adjustments in watchdog timing.

The output driver offers active low signaling with either open drain or push-pull configuration options, enabling flexible interfacing with various microprocessor systems. The device is housed in a miniature 8-pin SOT-23 surface mount package, measuring just 3mm in length, 1.75mm in width, and 1.3mm in height, which supports compact PCB designs.

Designed to operate in harsh environments, it supports a wide temperature range from -40°C to 125°C and complies with the automotive AEC-Q100 standard, assuring robustness and reliability in automotive-grade applications.

No external components are required for operation, simplifying design and reducing BOM costs. Additionally, the watchdog timer includes a disable feature for applications that require temporary suspension of monitoring.
