Maxim Integrated MAX6334UR18D3-T Voltage Supervisor

The MAX6334UR18D3-T is a precision voltage supervisor designed to maintain system integrity by monitoring the supply voltage of microprocessors (µPs) and digital systems. Manufactured by Maxim Integrated, a renowned leader in the development of integrated circuits, this device is crucial for ensuring that systems operate within their specified voltage ranges, and it helps to prevent data corruption and system failures that can occur during power-up, power-down, or brown-out conditions.

With a fixed-sense threshold voltage of 1.8V, the MAX6334UR18D3-T is suitable for low-voltage applications that require a tight regulation of the operating voltage. The device features an active-low reset output, which remains asserted until the supply voltage reaches the specified threshold and for a reset timeout period after the supply voltage exceeds the threshold. This ensures that the µP has sufficient time to stabilize before the system resumes operation.

The MAX6334UR18D3-T comes in a compact SOT-23 package, making it ideal for space-constrained applications. It has a wide operating temperature range from -40°C to +85°C, which allows for deployment in various environmental conditions. The device's low supply current of 20µA (typical) makes it an energy-efficient choice for battery-powered and portable devices.

Key features of the MAX6334UR18D3-T include:

• Precision factory-set V<sub>CC reset thresholds
• 140ms (min) reset timeout period
• Low, 20µA supply current
• Guaranteed reset valid to V<sub>CC = 1V
• Power supply transient immunity
• No external components required
• Compact SOT-23 packaging

This voltage supervisor is an essential component for systems that cannot tolerate any disruption or uncertainty in power supply, such as embedded systems, portable devices, and other digital electronics that require consistent monitoring and management of power supply conditions. The MAX6334UR18D3-T's reliability and precision make it a trusted choice for safeguarding critical electronic systems.
