Introduction to ADM691AR-REEL

ADM691AR-REEL is a supervisory circuit which integrates several monitoring, protection and control functions into one power management integrated circuit (PMIC). It is a low-power and low-voltage supervisor that monitors up to four supplies, each with a threshold of 0.33V. The device uses a precision bandgap reference voltage to monitor the voltage of each supply. If the voltage of a monitored supply falls below or exceeds a predetermined threshold, the monitor triggers a reset.

Applications of ADM691AR-REEL

ADM691AR-REEL is used to monitor and protect computer systems, microprocessors, embedded systems and system board components. It is designed to provide power-on reset, undervoltage monitoring and Brown-out reset for microcontrollers, memory and peripherals. The device can also be used for automatic power sequencing and power-on reset sequencing. The device is usually used in systems where multiple power supplies must be monitored for optimal system performance and reliability.

Benefits of ADM691AR-REEL

The ADM691AR-REEL is designed to be a low-power, low-voltage supervisor with numerous benefits. Its 2.2V bandgap reference voltage ensures reliable and accurate monitoring of multiple supplies. The device can be used to protect against power-on reset and undervoltage conditions. It also offers an adjustable reset delay time to accommodate slow power-on-rising output capacitors. The device is used in systems where multiple power supplies must be monitored for optimal system performance and reliability. The device also offers protection against latch-up and overcurrent conditions.

Working Principle of ADM691AR-REEL

The ADM691AR-REEL uses a precision bandgap reference voltage to monitor the voltage of each supply. When the monitored voltage falls below or exceeds a predetermined threshold, the monitor triggers a reset. The reset is triggered when the monitored voltage falls below the 0.33V threshold. An internal reset delay timer can be adjusted to accommodate slow power-on-rising output capacitors. The timer provides a reset delay time of up to 10 milliseconds. The device also includes overcurrent protection and latch-up protection. When an overcurrent condition or latch-up occurs, the device shuts down its outputs and triggers a reset.

Conclusion

The ADM691AR-REEL is a low-power and low-voltage supervisory circuit designed to monitor multiple power supply sources and protect against undervoltage conditions, overcurrent conditions and latch-up conditions. It uses a precision bandgap reference voltage to monitor the voltage of each supply and also offers adjustable reset delay time to accommodate slow power-on-rising output capacitors. The device is an ideal solution for systems where multiple power supplies must be monitored and protected for optimal system performance and reliability.
