Microchip Technology MIC809-5SYC3 Voltage Supervisor

The MIC809-5SYC3 is a highly precise voltage supervisor designed to monitor power supplies in digital systems. Manufactured by Microchip Technology, this compact and efficient component ensures that your electronic devices operate within safe voltage levels, thus protecting them from potential damage due to unexpected power fluctuations.

This voltage supervisor is particularly well-suited for battery-powered devices, microcontrollers, and other digital systems where power stability is crucial. The MIC809-5SYC3 is designed to assert a reset signal whenever the VCC supply voltage falls below a preset threshold of 4.63V (typical), ensuring reliable operation of the system it is monitoring. The reset signal remains active for a period after VCC has risen above the reset threshold, providing ample time for the system to stabilize.

Key features of the MIC809-5SYC3 include:

• Supply Voltage Monitoring: Precision monitoring at a threshold voltage of 4.63V, with tight accuracy, ensures that the device operates reliably under specified conditions.
• Low Power Consumption: With its low power draw, this voltage supervisor is ideal for power-sensitive applications, thereby extending the battery life of portable devices.
• Manual Reset Input: The inclusion of a manual reset input allows for external triggering of a reset, providing additional control to system designers.
• Reset Timeout: A built-in delay in the assertion of the reset signal ensures that the system has sufficient time to return to a stable state before normal operation resumes.
• Compact Package: The MIC809-5SYC3 comes in a small SOT-23 package, making it suitable for space-constrained applications.

With its built-in hysteresis, the MIC809-5SYC3 effectively prevents erratic reset operation when the supply voltage is around the threshold level. This feature is particularly important for environments with a high level of electrical noise, where voltage levels can fluctuate rapidly.

The integration of the MIC809-5SYC3 in your system ensures that all essential components are protected from the dangers of undervoltage conditions, thus improving the reliability and longevity of the product. Its precision, low power consumption, and compact form factor make it an excellent choice for a wide range of applications in the consumer, industrial, and automotive markets.
