Description and Introduction
2 A, High-Side P-Channel Switch with Current Limit and Thermal Shutdown The ADM869LARQ is a microprocessor (μP) supervisory circuit manufactured by Analog Devices. It is designed to monitor the power supply voltage of a microprocessor or microcontroller system and provide a reset signal if the voltage falls below a specified threshold. Key specifications include:
- **Reset Threshold Voltage**: Typically 4.65V for the 5V version. The ADM869LARQ is commonly used in applications requiring reliable power-on reset and power supply monitoring, such as embedded systems, industrial controls, and automotive electronics. |
