Description

The MAX6866UK29D3S+ is a precision voltage supervisor from Maxim Integrated (now part of Analog Devices). This device is designed to monitor power supply voltages and provide reliable over-voltage and under-voltage detection for various applications, including microcontrollers and other digital ICs.
Key features include a low supply voltage operation, a reset output that ensures proper system startup, and a fast response time to voltage fluctuations. The MAX6866 series offers programmable reset thresholds, making it adaptable to different system requirements. It also includes features like a manual reset input and a watchdog timer, enhancing system reliability.
The MAX6866UK29D3S+ is encapsulated in a compact 3-pin SOT-23 package, making it suitable for space-constrained designs. Its low power consumption and high accuracy make it ideal for battery-operated devices. Overall, this voltage supervisor is crucial for ensuring system stability and preventing malfunction due to power supply issues.

Features

The MAX6866UK29D3S+ is a precision voltage reference IC designed for high-performance applications. Key features include:
1. Output Voltage: Provides a fixed output voltage of 2.5V with a tolerance of ±0.5%.
2. Low Drift: Excellent temperature stability with a low temperature coefficient (typically 10 ppm/°C).
3. Low Noise: Low output voltage noise ensures clean reference voltage.
4. Supply Voltage: Operates over a wide supply voltage range (up to 15V).
5. High Output Drive: Capable of sourcing and sinking current, making it suitable for various loads.
6. Low Power Consumption: Designed for efficient operation, minimizing power usage.
7. Small Package: Available in a compact 3mm x 3mm TDFN package, facilitating space-saving designs.
