Power management integrated circuits (PMICs) are an integral element in the design of complex multi-chip systems. Supervisors include components such as voltage supervisors and reset controllers, which play a critical role in protecting the system from unwanted power-related issues. Recent advances have seen a vast increase in the amount of features available in these devices, allowing designers to optimize the performance and safety of their systems.

The PT7M3808G50TAEX is a general-purpose voltage supervisor and reset controller, specifically designed to handle a wide range of voltages in an operating temperature range of -40 to 125°C. This device provides an integrated monitoring and reset controller to ensure system reliability in the event of an abnormal voltage condition. It is widely used in the consumer electronics, industrial, and aerospace and defense industries, among others.

The PT7M3808G50TAEX is a small, low-power circuit which is optimized to provide superior performance and offer system reliability in the event of an abnormal voltage condition. It utilizes SuperSense® technology which allows the circuit to detect and monitor voltage with great accuracy and precision. Additionally, the device also features a low quiescent current operation, which reduces power consumption. This makes it well-suited for use in low-power and embedded applications.

The device features a configurable input power-on-reset (POR) and external reset input for system initialization and reset management. The external reset input provides additional flexibility for system reset, allowing it to be reset remotely in the event of an abnormal system condition. The POR and reset inputs are connected to an internal reset control logic block which manages the reset signals to ensure proper system operation.

The PT7M3808G50TAEX includes an on-chip timer which can be used to control the reset outputs. This timer ensures that the reset outputs remain activated for a minimum amount of time, allowing the system to exit a reset condition. Additionally, the reset outputs of the device can be selectively enabled or disabled using the manual reset control pin, allowing users to control the system reset when needed.

The PT7M3808G50TAEX is designed to provide superior voltage monitoring capability, allowing it to precisely monitor voltages from 0.9V to 5.5V with an accuracy of ±1%. This makes it suitable for monitoring both analog and digital power rails. Additionally, the device also features a range of adjustable voltage threshold levels that can be configured for different applications.

The PT7M3808G50TAEX also offers protection from ESD, EMI, and EOS events through its integrated protection circuitry. This allows the circuit to detect pulsed EMI and EOS events, while still providing a reliable reset output when required. This makes the device an ideal choice for use in applications that require reliable protection from EMI, EOS, or ESD events.

Overall, the PT7M3808G50TAEX is a versatile device which provides superior performance and system reliability. Its wide range of features make it well suited for use in a wide range of applications, including consumer electronics, industrial, automotive, and aerospace and defense. Additionally, its adjustable voltage threshold and low quiescent current operation make it ideal for use in low-power applications.
