概要

Description

The MAX6315US31D3 is a microprocessor supervisory circuit designed to monitor power supply voltages in microprocessor systems. It ensures that the system operates reliably by asserting a reset signal whenever the supply voltage falls below a predefined threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.
This particular model in the MAX6315 series features a precision voltage monitor with a threshold set to 3.1V. It provides a push-pull reset output, which is active low. The reset output remains asserted for a fixed timeout period after the supply voltage has stabilized, ensuring the system has adequate time to start up correctly.
The MAX6315US31D3 is housed in a compact SOT-23 package, making it ideal for space-constrained applications. It is commonly used in embedded systems, consumer electronics, and other applications requiring reliable voltage supervision. The low quiescent current of the device also makes it suitable for battery-operated devices, helping to preserve battery life.

Equivalent

The MAX6315US31D3 is a microprocessor supervisory circuit that provides reset functionality. Equivalent products include the Microchip MCP101-315, the Texas Instruments TPS3836H30, and the STMicroelectronics STM706T. These components offer similar functionalities like voltage monitoring and reset signal generation for microprocessors and microcontrollers. Always verify the specific parameters and package compatibility to ensure proper functionality for your application.

Features

The MAX6315US31D3 is a microprocessor supervisory circuit designed to monitor supply voltage levels and provide a reset signal to ensure proper system operation during power-up, power-down, or brownout conditions. Key features include:
1. Precision Monitoring: It monitors a single power supply voltage with a defined threshold, ensuring accurate and reliable reset signals.

2. Manual Reset Input: The device includes a manual reset input, allowing external control to initiate a reset.
3. Reset Timeout Delay: The reset output is delayed for a specified time, typically 200ms, to ensure stability before the system restart.
4. Active-Low Reset Output: The reset signal is active-low, which is compatible with most microprocessor designs.
5. Low Supply Current: With a low supply current, it is highly suitable for battery-powered applications.
6. Wide Operating Voltage Range: It operates over a broad range of supply voltages, enhancing its versatility across different systems.
Overall, the MAX6315US31D3 provides robust features suitable for safeguarding microprocessor operations in various electronic applications.

Pinout

The MAX6315US31D3 is a microprocessor supervisory circuit produced by Maxim Integrated. It typically comes in a SOT-23 package, which has a pin count of 5.
This device is designed to monitor the power supply to a microprocessor and to provide a reset signal to ensure proper operation. The MAX6315US31D3 monitors the supply voltage and asserts a reset signal whenever the supply voltage drops below a predetermined threshold (in this specific variant, the threshold is 3.1V). The reset signal remains asserted for a fixed timeout period after the supply voltage rises above the threshold, ensuring that the microprocessor has a stable power supply before it starts executing instructions.
Additionally, this device features a manual reset input, allowing an external push button or digital signal to trigger a reset. This is particularly useful for debugging or initializing systems manually. The compact size and functionality make the MAX6315US31D3 suitable for power-sensitive and space-constrained applications.
