Description
Key features include:
1. Voltage Monitoring: Supervises a 3.3V supply voltage with a typical threshold of 2.93V.
2. Reset Function: Provides an active-low reset signal when the monitored voltage drops below the threshold, ensuring the system remains in reset until stability.
3. Delay Time: Features a fixed reset delay time, allowing the power supply to stabilize before releasing the reset.
4. Low Supply Current: Offers low power consumption, suitable for battery-powered applications.
5. Compact Package: Available in a small SOT-23-5 package, which is ideal for space-constrained applications.
This device is essential in applications like microcontroller systems, ensuring reliable operation and protection from supply voltage anomalies.
Equivalent
1. Maxim Integrated's MAX809 series (e.g., MAX809S series for 3.3V applications).
2. ON Semiconductor’s MC33064 series.
3. Microchip's MCP130/131 series (e.g., MCP130-315).
4. STMicroelectronics' STM1001 series.
These alternatives provide similar functionality for voltage monitoring and reset in electronic applications. Always check specific electrical characteristics and pin compatibility when selecting a replacement.

Pinout
Here is a brief overview of its pin functions:
1. GND: Ground connection.
2. MR (Manual Reset Input): An input for manually triggering a reset when pulled low.
3. RESET: The reset output, which goes low when the monitored voltage falls below the threshold or when MR is activated.
4. VDD: Supply voltage pin.
5. NC (No Connection): There is no internal connection to this pin.
This IC is commonly used in applications requiring reliable system resets, such as in microcontroller-based systems.
