Microchip Technology's MIC809MUTR Supervisor IC

The MIC809MUTR from Microchip Technology is a highly reliable voltage supervisor IC designed to maintain system integrity by monitoring the power supply in digital systems. This compact component is an essential safeguard for microcontrollers and other digital circuits, ensuring that they are reset appropriately during power-up, power-down, and brown-out conditions.

This supervisor IC comes in a tiny 4-pin SOT-143 package, making it an ideal choice for space-constrained applications. Despite its small size, the MIC809MUTR packs a powerful punch, offering precision monitoring of 3-pin voltages with a factory-trimmed threshold. The reset output is active low and is asserted when the monitored voltage falls below the threshold, ensuring the connected microcontroller or processor is held in reset until stable conditions are detected.

Key features of the MIC809MUTR include:

• Supply Voltage Monitoring: Accurate monitoring of the supply voltage to ensure reliable operation of the system.
• Low Power Consumption: With its low power draw, this IC is suitable for battery-operated devices, contributing to extended battery life.
• Manual Reset Capability: The inclusion of a manual reset input provides designers with the flexibility to trigger a system reset as required.
• Immunity to Short VDD Transients: The device is designed to ignore brief glitches on the VDD line, which helps to prevent false resets.
• Fast Response Time: The MIC809MUTR responds quickly to voltage changes, ensuring timely system protection.
• Built-in Hysteresis: The hysteresis feature helps to prevent erratic resets due to noisy voltage levels.

The MIC809MUTR is an essential component for a broad range of applications, including computers, controllers, intelligent instruments, and portable electronics. Its ability to provide a reliable reset signal makes it a trusted choice for engineers looking to enhance the robustness and stability of their electronic designs. With its precision voltage monitoring and low power consumption, the MIC809MUTR is a smart addition to any power management solution.
