Product Overview: MAX696MJE/883B from Maxim Integrated

The MAX696MJE/883B is a high-quality, precision microprocessor (μP) supervisory circuit designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering. This device is specifically engineered to monitor power supplies in μP and digital systems, providing excellent reliability and performance for critical applications. It ensures that the system operates correctly by monitoring the power supply voltage and asserting a reset if the supply voltage drops below a predetermined threshold.

One of the standout features of the MAX696MJE/883B is its ability to provide a reset signal to the μP during power-up, power-down, and brown-out conditions. The reset output remains operational with VCC as low as 1V, and the reset threshold voltage can be precisely set by the user with external resistors. This flexibility allows the device to be tailored to specific system requirements, enhancing system stability and protection.

The MAX696MJE/883B also includes a watchdog timer that can be disabled if not required. This timer periodically requires a signal from the μP to prevent it from resetting the processor, ensuring the system continues to operate without stalling or running into an infinite loop. Additionally, the device provides a 1.25V threshold detector for power-fail warning, low-battery detection, or to monitor another power supply voltage.

Designed with versatility in mind, the MAX696MJE/883B is compatible with a wide range of supply voltages and is available in a hermetically sealed, 16-pin ceramic dual in-line package (CERDIP). This makes it suitable for military or aerospace applications that require stringent quality and reliability. The device operates over a wide temperature range and is designed to meet the rigorous standards of MIL-STD-883B, indicating its suitability for use in harsh environments and mission-critical applications.

In summary, the MAX696MJE/883B from Maxim Integrated is a robust, versatile, and reliable μP supervisory circuit that provides essential protection and monitoring for advanced digital systems. Its ability to customize threshold levels and its comprehensive feature set make it an ideal choice for designers looking to enhance system stability and safeguard against power anomalies.
