Description

The STM812LW16F is an electronic component belonging to the supervisors product category. It is a low-power supervisory device used for monitoring power supplies. Its function is to assert a reset signal when the VCC supply voltage drops below a preset value and to keep it asserted until VCC has risen above the preset threshold for a minimum period of time. Additionally, it provides a push-button reset input. This component is widely used in electronic circuits.

Specifications and features

• Precision monitoring of 3V, 3.3V, and 5V supply voltages
• Two output configurations: Push-pull RST Output (STM809/811) and Push-pull RST Output (STM810/812)
• 140ms reset pulse width (min)
• Low supply current - 6µA (typ)
• Guaranteed RST/RST assertion down to VCC= 1.0V
• Operating temperature: –40°C to 85°C (Industrial Grade)
• Lead-free, small SOT23 and SOT143 package

Application Scenarios

STM812LW16F is often used in electronic circuits where a precise monitoring of power supplies is required. It helps to assert a reset signal when voltage drops below the set threshold and maintain it until voltage rises above the set level. Additionally, it provides a push-button reset input making it easy to reset circuits.

Comparison

• Low supply current makes it an energy-efficient option for electronic devices
• It has a small SOT23 and SOT143 package, making it easy to integrate into very small electronic circuits
• Guaranteed RST/RST assertion down to VCC= 1.0V indicates its reliability even under low voltage conditions

• It only performs the single function of detecting and asserting reset signals for low voltage conditions.
• It may not be suitable for circuits where more advanced monitoring features are needed.
