STM817MM6E - Voltage Supervisor IC from STMicroelectronics

The STM817MM6E is a highly precise voltage supervisor IC designed to ensure the reliable operation of microprocessor (µP) systems. Manufactured by STMicroelectronics, a leader in semiconductor solutions, this device is integral in monitoring the power supply voltage of digital systems. It provides a reset signal to the µP during power-up, power-down, and brown-out conditions, safeguarding the system against improper operation at low voltage levels.

This voltage supervisor IC features a fixed threshold level of 4.63V, which is ideal for 5V powered applications. The reset output of the STM817MM6E is active low, and it is guaranteed to be in the correct state for Vcc down to 1.0V, ensuring the IC can handle a wide range of power supply variations with confidence. The device comes in a compact SOT-23 package, making it suitable for space-constrained applications.

The STM817MM6E also boasts a low supply current, making it an energy-efficient choice for battery-powered devices. Its fast response time ensures that the µP is reset promptly, avoiding any potential mishaps due to delayed response to power fluctuations. Additionally, the device's built-in hysteresis improves noise immunity, contributing to the overall robustness of the system.
