MIC8114TU Description

Short technical summary and product information.

The MIC8114TU from Micrel Inc. is an inexpensive supervisory circuit designed to monitor power supply levels in microprocessor-based systems. It asserts a reset signal when the power supply drops below a designated threshold or when the manual reset input (/MR) is activated.

Key electrical specifications include a typical supply current of 5µA and an operating voltage range from 1V to 5.5V. The reset voltage threshold is precisely set at 3.08V typical, ensuring reliable operation for 3.3V systems. The /RESET output remains asserted for a minimum of 790ms after VCC rises above the threshold, providing a robust reset pulse.

This device features a manual reset input (/MR) that can be driven by CMOS or TTL logic, or shorted to ground via a switch. It also includes internal pull-up resistance on the /MR input. The MIC8114TU is available in a compact 4-lead SOT-143 surface-mount package, making it suitable for space-constrained applications.

Applications for the MIC8114TU include portable equipment, intelligent instruments, critical microprocessor power monitoring, printers, computers, and embedded controllers. Its design ensures that the /RESET output remains valid even with VCC as low as 1V.
