Maxim Integrated MAX695EPE+ Microprocessor Supervisory Circuit
The Maxim Integrated MAX695EPE+ is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected conditions in digital systems. This essential component is engineered to monitor power supplies in µP and digital systems, providing a significant layer of protection against low-voltage and faulty operation. It is an ideal choice for use in microprocessor systems, computers, controllers, and intelligent instruments where data integrity is crucial.
The MAX695EPE+ offers a variety of features that make it a versatile solution for system management. It incorporates a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum of 200ms after VCC has risen above the reset threshold level, ensuring that the µP starts up in a known state. Additionally, the device includes a watchdog timer that can be set by an external capacitor, which helps to ensure that if a system becomes unresponsive or hangs, the watchdog can trigger a system reset.
This supervisory circuit also provides a 1.3V threshold detector for power-fail warning, low-battery detection, or to monitor a power supply other than +5V. The chip-select gating feature (active-low CE IN and active-low CE OUT) further enhances the functionality of the MAX695EPE+, allowing for memory write protection during power failures or when the watchdog timer has expired.
Encased in a 16-pin DIP (Dual In-line Package), the MAX695EPE+ is designed for easy integration into a wide range of applications. It operates over a wide temperature range, making it suitable for industrial applications. The device requires minimal external components, which simplifies design and increases system reliability.
By utilizing the MAX695EPE+ in your digital system, you can ensure that your microprocessor is protected from the unpredictable nature of power supplies, thereby preserving system integrity and preventing data corruption. Maxim Integrated's commitment to quality means that you can rely on the MAX695EPE+ to provide robust and consistent performance.
