Working Principles

The MC34164DM is designed to monitor the supply voltage of a microprocessor or other digital systems. It continuously compares the supply voltage against a user-adjustable threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a power failure or low voltage condition. The reset output remains active until the supply voltage rises above the threshold or a manual reset signal is received.

Detailed Application Field Plans

The MC34164DM is widely used in various applications where reliable voltage monitoring is crucial. Some of the common application fields include:

  1. Microcontrollers and microprocessors
  2. Embedded systems
