The MIC6315 is an inexpensive open-drain microprocessor reset circuit ideal for monitoring power supplies in microprocessor-based systems. It asserts a reset signal if the power supply voltage falls below a preset threshold or if the manual reset input (/MR) is triggered. The MIC6315 offers precision voltage monitoring, a low supply current, and selectable reset pulse widths, making it suitable for portable equipment, intelligent instruments, and embedded controllers. Its open-drain output and manual reset feature provide flexibility in system design and fault recovery.
