Maxim Integrated MAX6365HKA29+T Microprocessor Supervisory Circuit
The MAX6365HKA29+T from Maxim Integrated is a high-quality 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 offers a variety of features to ensure that your system remains functional and protected. Its primary function is to assert a reset signal whenever the VCC supply voltage declines below a preset threshold, ensuring that the µP starts up in a known state. The reset signal is maintained for a minimum timeout period after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.
The MAX6365HKA29+T features a factory-trimmed reset threshold suited for operation with a 2.93V supply voltage, which is ideal for low-voltage applications. The device's reset output stage is push-pull, which eliminates the need for an external pull-up resistor and ensures a strong low signal when asserted. Additionally, the reset active timeout period is fixed at 140ms (min), providing a predictable delay before system operations resume after a reset condition.
This device is available in a small SOT-23 package, making it suitable for space-constrained applications. It operates over a wide temperature range of -40°C to +125°C, ensuring reliability across various environmental conditions. The MAX6365HKA29+T is also characterized for lower supply voltages down to 1V, providing versatility in different power scenarios.
Maxim Integrated's MAX6365HKA29+T is a smart choice for managing power-on reset and power-fail conditions in microcontrollers, computers, controllers, and intelligent instruments. Its combination of features, compact size, and robust design makes it an essential component for ensuring the integrity and stable operation of your digital systems.
For designers and engineers looking for a dependable solution to safeguard their digital systems against power instability, the MAX6365HKA29+T offers the reliability and performance needed for smooth and secure operations.
