概述

Description

The MAX6315US29D3+T is a microprocessor supervisory circuit designed by Maxim Integrated. It is part of the MAX6300 series, which provides essential monitoring functions for microprocessor systems. This particular model offers a precise reset threshold voltage of 2.9V, ensuring that microprocessors operate within safe voltage levels. The device generates a reset signal when the monitored voltage drops below this threshold, thereby preventing erratic system behavior during power fluctuations or brownout conditions.
Key features of the MAX6315US29D3+T include a low supply current, typically around 3µA, and a reset timeout period of 200ms, which ensures system stability before normal operation resumes. It is available in a compact SOT-23 package, making it suitable for space-constrained applications. The device is ideal for use in battery-powered equipment, embedded systems, and other applications requiring reliable power supervision and reset signal generation. Its robustness and low power consumption make it a valuable component in ensuring the safety and stability of electronic designs.

Features

The MAX6315US29D3+T is a microprocessor supervisory circuit designed to monitor supply voltages. Key features include:
1. Supply Voltage Monitoring: It ensures reliable operation by monitoring the supply voltage of microprocessors.
2. Reset Functionality: Provides a reset output to initiate a reset when the monitored voltage falls below a preset threshold.
3. Threshold Voltage: This particular model has a reset threshold of 2.9V.
4. Output Type: Features an active-low, push-pull reset output.
5. Reset Timeout: It typically has a fixed reset timeout period to ensure enough time for the system to stabilize after a power-up.
6. Package: Available in a compact SOT-23 package, suitable for space-constrained applications.
7. Temperature Range: Operates over a wide temperature range, ensuring reliability in various environmental conditions.
8. Low Power Consumption: Designed to consume minimal power, making it ideal for battery-operated devices.
These features make the MAX6315US29D3+T suitable for use in portable and consumer electronics, where reliable voltage monitoring and reset functionality are critical.

Package

The MAX6315US29D3+T is a microprocessor supervisory circuit from Maxim Integrated. It comes in a SOT-23-5 package, which is a small outline transistor package with five pins, designed for surface mounting on a printed circuit board.

Pinout

The MAX6315US29D3+T is a supervisory circuit designed to monitor system voltages and provide a reset signal for microprocessors and digital systems to ensure proper operation during power-up, power-down, and brownout conditions. This device comes in a small SOT-23-5 package, which indicates it has 5 pins.
Key functions of the MAX6315US29D3+T include:
1. Voltage Monitoring: It monitors a 2.9V system voltage; if the voltage drops below this threshold, the device asserts a reset signal.
2. Reset Output: Provides a reset signal to the microprocessor, which remains asserted for a fixed duration after the monitored voltage returns above the threshold.
3. Manual Reset Input: May feature an input pin for an external, manual reset signal.
4. Active-Low Reset: Typically, the reset output is active-low, ensuring compatibility with most microprocessor reset input requirements.
Always refer to the manufacturer's datasheet for precise specifications and pin configurations.
