Functional Features

• Accurate voltage monitoring: The MIC2012PCM-TR continuously monitors the power supply voltage and compares it with the preset threshold voltage.
• Reset generation: When the power supply voltage falls below the threshold voltage, the MIC2012PCM-TR generates a reset signal to initiate system reset or shutdown.
• Manual reset input: The MR pin allows for manual reset control, overriding the automatic reset generation.
• Adjustable threshold voltage: The TH pin provides options to select different threshold voltages according to specific system requirements.

Advantages and Disadvantages

Advantages: - Ensures stable operation of electronic systems by monitoring power supply voltages - Small form factor enables integration into space-constrained designs - Wide operating temperature range allows for use in various environments - Low power consumption minimizes energy usage

Disadvantages: - Limited threshold voltage options may not cater to all voltage monitoring needs - Lack of additional features such as hysteresis adjustment

Working Principles

The MIC2012PCM-TR operates by continuously monitoring the power supply voltage using an internal voltage reference. It compares the monitored voltage with the preset threshold voltage selected through the TH pin. If the power supply voltage falls below the threshold voltage, the IC generates a reset signal on the RESET pin, initiating a system reset or shutdown. The manual reset input (MR) allows for manual control over the reset function, overriding the automatic reset generation.

Application Field Plans

The MIC2012PCM-TR finds applications in various electronic systems where accurate voltage monitoring and reset generation are critical. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Power management circuits - Industrial automation systems - Automotive electronics
