XC6109N49ANR-G

The XC6109N49ANR-G supervisor is a device that regulates and supervises power management in electronic circuits. It is part of a family of integrated circuits predominantly used in power management applications, such as voltage supervisors, low voltage detectors, and reset circuits. The XC6109N49ANR-G provides a reliable, low power, reset circuit for microprocessors, DSPs, and microcontrollers to ensure proper operation in the event of a power failure, brownout, or system reset. This device is especially beneficial when used in remote field applications with unstable power (such as unused or low line-voltage conditions).

The XC6109N49ANR-G is a supervisor that monitors the VDD power line and provides a reset signal if the voltage level drops below a preset threshold. This device has a low voltage detect feature that is activated when the voltage falls below a certain low limit, while the reset feature is activated when the voltage falls below a certain upper limit. The reset feature is usually triggered by a power on reset (POR) signal, which is generated when the voltage rises beyond the preset threshold.

The XC6109N49ANR-G is ideal for applications in many industries, including mobile communications, automotive, medical, and aerospace. In mobile communications, for example, the device is used to detect low battery conditions and generate an interrupt signal to the system. In automotive, the device is often used in engine control systems to detect a power interruption and reset the system in order to prevent vehicle damage or malfunction. In medical applications, the XC6109N49ANR-G is used to detect power- related anomalies, such as brownouts or power surges, and reset the equipment in order to protect it from damage. Additionally, the device is used in aerospace systems to detect low-voltage supply issues and reset the system prior to a mission-critical event.

The XC6109N49ANR-G is a single-chip device, meaning that it incorporates all the functionalities of a supervisor on one chip. It operates with a low operating current of 10μA and includes a watchdog timer circuit to provide an automatic reset output when the voltage fails to reach its set threshold. It also offers protection against both overvoltage and undervoltage conditions and provides a power-on reset output when the device powers up.

The XC6109N49ANR-G works by monitoring the input DC power supply (V DD ) and the battery voltage (V BAT ). When the input voltage falls below the preset threshold, the reset output is triggered to reset the system. The reset output can be delayed using the watchdog timer circuit in order to prevent excessive resetting and allowing the system sufficient time to operate before resetting. The device also features hysteresis, meaning that the preset threshold is adjustable, allowing the user to set the desired voltage.

The XC6109N49ANR-G supervisor is a reliable, cost-effective solution for low voltage detection and system reset in a wide range of industrial, automotive, and medical applications. With its low operating current and adjustable hysteresis, the XC6109N49ANR-G is an ideal solution for power management applications that require a simple reset circuit.
