Maxim Integrated MAX802LEPA Microprocessor Supervisory Circuit

The Maxim Integrated MAX802LEPA is a highly efficient supervisory circuit designed to monitor the power supplies in microprocessor and digital systems. It provides a precise, low-cost method to ensure that the microprocessor's power supply is stable before the processor is allowed to execute code. This is essential for preventing system errors and data corruption that can occur if a system attempts to operate with an unstable power supply.

The MAX802LEPA offers several key features that make it an ideal choice for a variety of applications. Its primary function is to monitor the system voltage and assert a reset if the voltage drops below a predetermined threshold. This reset output ensures that the microprocessor restarts cleanly once the supply voltage returns to a safe level. The device's reset timeout is pre-set, which allows for a predictable delay before the system attempts to restart, providing additional stability.

Another notable feature of the MAX802LEPA is its low power consumption, making it suitable for power-sensitive applications. It has a typical supply current of only 20µA, which is beneficial for battery-operated devices where power efficiency is critical. Additionally, the supervisory circuit operates over a wide voltage range and temperature range, offering reliable performance in diverse environments.

The MAX802LEPA comes in a compact 8-pin DIP package, which is easy to integrate into existing designs. Its small footprint allows for it to be used in space-constrained applications without sacrificing performance. The device also includes a manual reset input, which provides a convenient way to initiate a system reset without needing to cycle the power supply.

Overall, the Maxim Integrated MAX802LEPA is an essential component for system reliability. It guards against power instability and ensures that digital systems, including microprocessors, operate within their intended voltage parameters. Its combination of features, including low power consumption, wide operating range, and compact size, make it a versatile choice for designers looking to enhance system integrity in their digital and microprocessor-based applications.
