Power Management Integrated Circuits (PMICs) are used for effective management of on-chip and/or off-chip power supply networks. PMICs represent a component of the core power management design architecture and have achieved an increased presence in the integrated circuit market. A supervisor is an application of a PMIC that monitors operating states of multiple system functions and takes appropriate measures to reset the system back to the known working state when an error condition is encountered.

TPS3711DDCR is a family of multi-channel power supervisor devices designed for operations in digital power solutions. It is an industry-leading power-on reset (POR) supervisor that provides a reliable solution for reset initialization and monitoring of multiple system components that require robust and accurate reset control.

Applications of the TPS3711DDCR include but are not limited to energy storage systems, networking systems, graphics cards, and other applications where a high level of reliability is required from the reset processing. The versatility of the device makes it suitable for a range of different applications, with distinct features that make it well suited for use in different configurations.

The TPS3711DDCR has a variety of features that make it the ideal solution for multiple types of systems. The device provides a precision reset delay timer and threshold hysteresis detection along with watchdog timer support. This can be used to detect and avoid a hard reset when errors occur and system malfunctions are detected. Additionally, the device has an internal power-on reset (POR) reference, which is accurate and reliable, minimizing input power issues.

The TPS3711DDCR has a dynamic power-on reset (DPR) feature that is responsible for resetting overload circuits and providing fault-tolerant protection of connected circuits. This feature is triggered when one of the assigned channels on the device detects a voltage exceeding the predetermined DPR threshold. When this happens, the device undergoes an instantaneous reset, protecting other system components from further damage.

The TPS3711DDCR is designed to monitor multiple voltage sources and can be configured for simultaneous monitoring for up to eight different DC sources. The device also features an open drain output, allowing for a high voltage output when the preset voltage threshold is exceeded. This also improves the overall power savings, as the device shuts off when the intended voltage level is reached.

The TPS3711DDCR has a clear and comprehensive configuration menu that provides a user-friendly interface and a range of control settings. With this, users can easily adjust the reset timeout interval and reset capture select thresholds. This interface also allows the user to monitor the relative voltage between two channels and set the delay timer duration in either minutes, hours, or seconds.

The on-chip watchdog timer feature is responsible for ensuring operational stability throughout the system. This feature can be set to trigger a reset after an interval, preventing unexpected system lock ups. When enabled, the input voltage must remain above the predetermined minimum voltage level to ensure reliability and accuracy.

The TPS3711DDCR is a versatile, powerful and reliable power supervisor for digital power solutions. With features like a POR reference, DPR circuit protection and a watchdog timer, it provides protection and accuracy for a range of different applications. Additionally, its user-friendly configuration menu allows users to easily adjust settings and monitor the relative voltages between channels, providing an efficient, reliable and flexible solution.
