概要

Description

The MAX809MEUR-T is a voltage supervisor designed to monitor power supply levels in microcontroller and other digital applications. It operates as a reset generator, ensuring that the system remains stable during power fluctuations. The device features a precision voltage threshold, typically set at 4.38V, triggering a reset when the voltage falls below this level.
Key features include fast response time, low supply current, and the ability to reset the microcontroller when power is restored. It is housed in a small 5-pin SOT-23 package, making it suitable for space-constrained applications. The MAX809MEUR-T is ideal for battery-powered devices, automotive electronics, and any system requiring reliable voltage monitoring and reset functions.
Overall, this component enhances system reliability by preventing erratic behavior during voltage dips and ensuring a clean start-up after power restoration.

Features

The MAX809MEUR-T is a voltage supervisor designed for low-voltage applications. Key features include:
1. Voltage Monitoring: It monitors supply voltages, providing a reset signal if the voltage falls below a specified threshold.
2. Reset Output: Active-low reset output that remains low during power-up, brownout, or voltage dips.
3. Adjustable Thresholds: Available with various fixed reset thresholds, typically around 2.63V or 3.08V.
4. Fast Reaction Time: Quick response time to voltage changes helps maintain system stability.
5. Low Power Consumption: Designed for battery-operated and low-power applications.
6. Small Package: Offered in a 5-pin SOT23 package, suitable for space-constrained designs.
7. Temperature Range: Operates over a wide temperature range, typically -40°C to +125°C.
8. No External Components Required: Simplifies design and integration.
These features make the MAX809MEUR-T an efficient choice for ensuring reliable operation in various electronic systems.

Package

Pinout

The MAX809MEUR-T is a voltage supervisory circuit with a pin count of 5. It is designed to monitor supply voltages and provide reset signals when the voltage falls below a predefined threshold. The pin functions are as follows:
1. Pin 1 (GND): Ground connection.
2. Pin 2 (RESET): Active-low reset output; goes low when VCC falls below the reset threshold.
3. Pin 3 (VCC): Supply voltage input; the monitored voltage.
4. Pin 4 (NC): No connection; not used.
5. Pin 5 (RESET_INPUT): External reset input pin for manual reset.
The device ensures reliable operation in microcontroller applications by preventing malfunction during power-down or brown-out conditions.
