Maxim Integrated MAX6334UR17D3+T Voltage Supervisor IC

The MAX6334UR17D3+T from Maxim Integrated is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 3.3V-powered circuits.

This compact supervisor IC ensures that the µP's power supply voltage is stable before allowing it to operate. It does this by asserting a reset signal whenever the VCC supply voltage falls below a preset threshold, 1.70V for the MAX6334UR17D3+T variant. The reset signal continues to be asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring the system has sufficient time to stabilize.

The device comes in a small SOT-23 package, making it ideal for space-constrained applications. The MAX6334UR17D3+T is capable of operating over a wide temperature range of -40°C to +125°C, which allows for use in environments that experience extreme temperature variations.

Key features of the MAX6334UR17D3+T include:

• Preset VCC Reset Threshold of 1.70V
• ±1.5% Reset Threshold Accuracy Over Temperature
• Immune to Short VCC Transients
• Low Power Consumption (20µA at 1.8V)
• 140ms (min) Reset Timeout Period
• Guaranteed Reset Valid to VCC = 1V
• Operational Temperature Range: -40°C to +125°C
• Available in a Small SOT-23 Package

With its built-in glitch immunity, the MAX6334UR17D3+T ensures that the µP reset input will remain in a reset state without false triggering, even during short duration transients on VCC. This feature is essential for systems that require a high degree of reliability and uptime.

Overall, the Maxim Integrated MAX6334UR17D3+T is a robust and reliable solution for system designers looking to enhance the operational stability of their digital systems. Its precision voltage monitoring and extended temperature range make it a versatile choice for a wide array of applications, from consumer electronics to industrial control systems.
