The XC6124D750MR-G is a member of the PMIC Supervisors product family from SMSC. It is a versatile, dual-channel voltage monitoring device with a wide variety of features and benefits that make it suitable for a variety of applications. This article will discuss the application field and working principle of the XC6124D750MR-G.

The XC6124D750MR-G is able to monitor two independent DC input voltages with selectable thresholds. The device is ideal for monitoring the on-chip voltage rails, system voltage rails and power rails in portable handheld or embedded designs. It can detect power supply overvoltage or undervoltage conditions, as well as open-circuit fault conditions. The device includes an integrated active power-on reset circuit that can provide a reset output when it detects an out-of-range condition. The reset output is driven active low and is typically connected to a microcontroller reset line. The reset feature can be enabled or disabled using the on-board digital control interface.

The XC6124D750MR-G has two overvoltage and two undervoltage comparators that can detect a wide range of input conditions. The overvoltage threshold and undervoltage threshold can be programmed to any value between 2.25V and 10V. The device also has a programmable power-on reset delay of up to 128ms. The device has a status output indicating whether the monitored voltage was in or out of range when it last checked. The status output can be connected to an external microcontroller to easily identify power supply fault conditions.

The device includes a dedicated test pin that can be connected to a logic high or low level to generate a simulated OV/UV condition. This allows designers to easily test and validate the reset circuitry in their application. In addition, the device includes a dedicated open drain reset output pin that indicates the current system power-on reset status.

The XC6124D750MR-G is designed to switch off the system in the event of an overvoltage or undervoltage condition by driving the reset output active low. This allows for a clean and safe shutdown of the system to prevent any damage from occurring in these conditions. The device also has an integrated power-on reset delay that ensures that the system will remain off until the supply voltage stabilizes to a safe voltage level.

The XC6124D750MR-G is a versatile, high-performance supervisor device that is suitable for use in a variety of applications. It provides dual-channel voltage monitoring and power-on reset functionality, and its wide input voltage detection range makes it a great choice for applications ranging from cellular phones to embedded systems.

The XC6124D750MR-G is a reliable and cost-effective solution for power system monitoring and power-on reset applications. It offers a wide operating temperature range of -40°C to +85°C and can withstand an input voltage range from +2.25V to +10V. Its integrated reset circuitry and programmable thresholds make it a great solution for a wide range of applications.
