The MIC6315-30D2UY-TR is a reset generator circuit that monitors power supplies in microprocessor-based systems. It is designed to assert a reset signal if the power supply drops below its nominal reset threshold of 3.00V. The device features an active-low, open-drain output that is guaranteed to remain asserted for a minimum of 20ms after VCC has risen above the threshold. With a low supply current of 5µA and a manual reset input, it offers efficient and flexible power supervision. Housed in a 4-lead SOT-143 package, this circuit is ideal for applications like portable equipment, embedded controllers, and other critical power monitoring scenarios.
