Maxim Integrated MAX6837FXSD3+T Voltage Supervisor IC

The MAX6837FXSD3+T from Maxim Integrated is a compact, highly reliable voltage supervisor IC designed to monitor power supplies in microprocessor systems. It provides a precise, low-power solution for systems that require voltage monitoring to ensure stable and secure operation. This component is ideal for use in a wide range of applications, including portable devices, computers, embedded systems, and industrial equipment.

The MAX6837FXSD3+T is part of Maxim Integrated's MAX6837 series, known for their low supply current and small footprint. The device operates over a wide voltage range, making it versatile for different power supply configurations. It features a fixed-sense threshold voltage of 3.08V, which is ideal for supervising 3.3V power supplies.

This voltage supervisor IC is designed to assert a reset signal whenever the VCC supply voltage falls below the preset threshold, ensuring that the microprocessor and other critical components are reset properly during power-up, power-down, or brown-out conditions. The reset output remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold, allowing the system to stabilize before operation resumes.

The MAX6837FXSD3+T comes in a compact, 5-pin SOT-23 package, which is suitable for space-constrained applications. It also features a low supply current of only 1.5µA, making it an energy-efficient choice for battery-powered devices. The device's operating temperature range of -40°C to +125°C ensures reliable performance in harsh environments.

Key features of the MAX6837FXSD3+T include:

• Fixed reset threshold voltage: 3.08V
• Low supply current: 1.5µA
• Minimum reset timeout: 140ms
• Wide supply voltage range
• Compact 5-pin SOT-23 package
• Operating temperature range: -40°C to +125°C

Maxim Integrated's commitment to quality ensures that the MAX6837FXSD3+T voltage supervisor IC is a reliable component for maintaining system integrity through power fluctuations. With its precision monitoring and low-power consumption, this IC is an excellent choice for designers looking to enhance the resilience and efficiency of their electronic systems.
