Maxim Integrated MAX6380UR42-T Voltage Supervisor

The MAX6380UR42-T is a high-quality voltage supervisor from Maxim Integrated, designed to provide precision monitoring of power supplies. This compact and reliable component is an essential part of any system that requires a stable and dependable voltage supply to ensure optimal performance and protection against power-related issues.

With a nominal threshold voltage of 4.2V, the MAX6380UR42-T is specifically engineered to supervise a 4.2V power supply. It offers a tight threshold accuracy of ±1.5%, which is crucial for systems that cannot tolerate significant voltage deviations. This accuracy ensures that the supervisor will trigger a reset or provide a warning signal only when the voltage actually goes out of the predefined safe operating range.

The device comes in a tiny SOT-23 package, making it ideal for space-constrained applications. Despite its small size, it does not compromise on performance and reliability. It operates over a wide temperature range of -40°C to +125°C, which makes it suitable for use in various environments, from industrial to automotive applications.

One of the key features of the MAX6380UR42-T is its low supply current, which is typically just 1.2µA at +25°C. This makes it an energy-efficient choice for battery-operated devices, as it minimizes power consumption and helps to extend battery life. The device's power-on reset delay time is fixed at 140ms, providing a predictable and consistent startup sequence for the monitored system.

Moreover, the MAX6380UR42-T includes an active-low, push-pull reset output. This design ensures that the reset signal is both robust and clearly interpretable by the system being monitored, without the need for external pull-up resistors. The device guarantees a minimum reset output duration of 140ms when VCC falls below the reset voltage threshold, providing ample time for the system to respond appropriately to voltage anomalies.

In summary, the Maxim Integrated MAX6380UR42-T voltage supervisor is a high-precision, low-power, and compact solution for monitoring 4.2V power supplies in a wide range of applications. Its accuracy, reliability, and energy efficiency make it an excellent choice for designers looking to enhance system stability and protection.
