PMIC – Supervisors are integrated circuits (ICs) that are mainly used to monitor power that is supplied to microcontrollers, processors, and system-on-chip designs. Supervisors act as a static check or monitor, that permits a controller to start-up and shut down systems safely. The ‘ADM1815-10ARTZ-RL’ is a supervisor IC, which is widely used in automotive and commercial applications.

One of the key benefits of the ‘ADM1815-10ARTZ-RL’ is its ability to provide over-current protection for redundant supplies. This feature is particularly useful in automotive applications, as it increases overall system reliability by reducing the likelihood of damage due to over-current scenarios. In addition, the supervisor IC also offers temperature sensing, allowing it to monitor the operating temperature of individual components and sending an alert, if the temperature exceeds a set threshold.

The device’s design also emphasizes low power consumption, as it features a low-power disconnect/reset circuit that operates directly from the power supply voltage, without the need for an additional regulation voltage (VREG). This feature allows the supervisor IC to reduce power consumption and extend the battery life of a system.

The ADM1815-10ARTZ-RL is a highly configurable device with a wide range of adjustable parameters and settings. The supervisor IC can be configured to determine accurate high voltage thresholds for dedicated applications, such as automotive pre-charging, as well as low voltage thresholds for detecting undervoltage conditions. The IC can also be programmed for manual or automatic loop-back testing, to ensure outstanding product reliability.

In terms of operation, the ADM1815-10ARTZ-RL works by constantly monitoring supply voltages and regulating these inputs to within acceptable levels. The IC incorporates selective power-up sequencing and a control logic block to automatically initiate a power-up sequence, when the power supply voltage reaches the predetermined threshold. During power-down, the IC will deactivate the power output circuits in a controlled manner, to prevent any sudden shutdowns or power supply glitches.

The ADM1815-10ARTZ-RL supervisor IC is an advanced and highly flexible solution for automotive and commercial applications. The IC offers a range of features, including: over-current protection, temperature sensing, low power consumption, selective power-up sequencing, as well as adjustable voltage thresholds and a loop-back testing feature. These features make the ADM1815-10ARTZ-RL an ideal choice for reliable and robust monitoring of power supply voltages.
