Functional Features

• Voltage monitoring: The MIC2536-1BMM continuously monitors the power supply voltage and generates a reset signal when it falls below the adjustable threshold.
• Adjustable threshold: The threshold voltage can be adjusted using an external resistor, allowing flexibility in setting the desired voltage level for triggering the reset signal.
• Manual reset: The MIC2536-1BMM provides a manual reset input (MR) that allows an external signal to force a reset, overriding the voltage monitoring function.
• Power-saving mode: The low quiescent current consumption of the MIC2536-1BMM ensures minimal power loss during operation.

Advantages and Disadvantages

Advantages

• Precise voltage monitoring ensures reliable operation of electronic devices.
• Adjustable threshold allows customization according to specific requirements.
• Small package size enables space-efficient integration into various applications.
• Low quiescent current consumption minimizes power wastage.

Disadvantages

• Limited number of pins may restrict the functionality in complex systems.
• Lack of built-in protection features against voltage spikes or transients.

Working Principles

The MIC2536-1BMM operates by comparing the power supply voltage with the adjustable threshold voltage. When the power supply voltage drops below the threshold, the reset output is activated, signaling the need for a system reset. The threshold voltage can be set using an external resistor connected to the TH pin. In addition, the manual reset input (MR) allows for an external signal to trigger a reset, bypassing the voltage monitoring function.
