Description

The DM860-TE is an electronic component model in the IC Chips category. It is a supervisory circuit designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. The circuit generates a power-on-reset signal when the supply voltage rises to a preset threshold level. It also features a debounced manual reset input that can be used to initiate a reset using an external push-button or logic signal. Additionally, it includes an on-chip watchdog timer to reset the microprocessor if it fails to strobe within a preset timeout period.
