Microchip Technology MIC811JUY-TR Voltage Supervisor IC

The MIC811JUY-TR from Microchip Technology is a highly reliable voltage supervisor integrated circuit (IC) designed to provide precision monitoring of power supplies. This compact and efficient device is an essential component for systems that require consistent and accurate voltage supervision to ensure stable and reliable operation. The MIC811JUY-TR is particularly suitable for applications such as microprocessor and microcontroller systems, battery-powered equipment, and intelligent instruments where power supply integrity is critical.

Featuring a 4.38V threshold voltage, the MIC811JUY-TR is adept at monitoring the power supply voltage and initiating a system reset when necessary. Upon detecting a voltage that falls below the specified threshold, the IC generates a reset signal that lasts for a minimum of 140ms, providing the system with ample time to return to a known state and prevent any erroneous operation. This reset signal ensures that the system can recover smoothly from power fluctuations or brown-out conditions.

The MIC811JUY-TR is available in a compact SOT-23-5 package, making it an ideal choice for space-constrained applications. Its low power consumption and wide operating temperature range of -40°C to +85°C make it versatile for use in various environments, from industrial settings to consumer electronics. Furthermore, the device supports a supply voltage range from 1.0V to 5.5V, catering to a broad spectrum of power requirements.

This voltage supervisor IC also boasts an active-low RESET output, which remains asserted for the duration of the reset timeout period. The push-pull output configuration eliminates the need for an external pull-up resistor, simplifying the design and reducing component count. Additionally, the MIC811JUY-TR offers excellent immunity to short duration transients on the monitored supply, enhancing the overall robustness of the system it protects.

Overall, the MIC811JUY-TR from Microchip Technology is a reliable and efficient solution for system designers looking to incorporate a cost-effective, precision voltage supervisor into their power management schemes. Its ease of integration, combined with Microchip's reputation for quality and support, makes it a top choice for safeguarding sensitive electronic systems.
