Maxim Integrated MAX6701SKA+T Microprocessor Supervisor

The MAX6701SKA+T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered circuits.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6701SKA+T monitors the supply voltage and keeps the µP in reset until that supply voltage reaches a stable operating level and maintains it for a minimum period (typically 140ms). The reset output remains operational with VCC as low as 1.2V, which is essential for low-voltage applications.

Featuring a factory-trimmed reset threshold, the MAX6701SKA+T provides a precision monitoring solution for systems operating at 5V. The device comes in a compact SOT-23 package, making it ideal for space-constrained applications. Its small size and high level of integration make it perfect for portable devices, embedded systems, and other applications where size and reliability are critical.

Key specifications of the MAX6701SKA+T include:

• Reset Threshold Voltage: Factory-trimmed for 5V systems
• Reset Timeout: Minimum 140ms reset pulse width ensures proper system reset
• Supply Voltage Range: Operates down to 1.2V for reset functionality
• Low Supply Current: Ideal for battery-powered equipment
• Package: Available in a small SOT-23 package
• Temperature Range: Operates over an extended temperature range

With its built-in watchdog timer, the MAX6701SKA+T can also monitor software execution within the µP, ensuring the system operates as expected. If the software fails to provide a periodic signal to the watchdog circuit, the device will issue a reset, helping to recover from software lock-up conditions.

In summary, the Maxim Integrated MAX6701SKA+T is a robust µP supervisory circuit that offers a mix of low power consumption, small size, and precision monitoring, making it a versatile choice for ensuring system stability in a wide range of applications.
