Power management integrated circuits (PMICs) are integrated circuits that provide power management functions. PMICs are designed to improve the error rate, reduce power consumption and improve system reliability. Supervisors (or voltage supervisors) are one type of PMICs, commonly referred to as reset ICs, resetting ICs, or system reset ICs, used to safeguard microprocessors, logic systems, and system bus drivers. The X5045S8I-2.7T1 supervisor is a highly integrated and extremely low-power device specifically designed for system reset and power-on reset (POR) applications.

Application Field

The X5045S8I-2.7T1 supervisor is a single-channel voltage supervisor device with independent reset generation and monitoring. It is used for system reset, delay reset, power-on reset, watchdog timer reset and system power off reset applications in a variety of systems. These systems include but are not limited to portable electronic devices, point-of-sale terminals, notebook computers, handheld devices, set-top boxes, digital cameras, television systems and embedded system applications. This supervisor IC is an ideal choice for power supply reset applications, with an operation voltage range of 1.8V to 5.5V and a voltage accuracy of only 0.8V. The device offers a reset-delay time of 1.1ms and a reset-pulse width of 60us.

Working Principle

This X5045S8I-2.7T1 supervisor operates by continuously monitoring the power supply voltage of the system and generating an active-low reset signal when the power supply voltage falls below the reset voltage threshold. The reset signals are output via the RESET pin, and can be used to reset embedded microprocessors, logic systems, and system bus drivers. The supervisor also features an open-collector topology, which allows multiple devices to connect to the device and share the same reset signal. The device also features a watchdog timer reset function, which can be used to generate a reset signal when the system does not respond in a timely manner.

The X5045S8I-2.7T1 supervisor IC also offers an independent power-on reset function. This function provides a reset signal when the system power is turned on and enables the system to reset the system to the initial state. In addition, the device also features an ultra-low power consumption mode that can be enabled in order to reduce power consumption by up to 85%. This power saving mode is enabled by pulling the RST signal low.

The X5045S8I-2.7T1 supervisor is a reliable reset IC that provides advanced system protection, such as reset signal delay and watchdog timer reset, and low power consumption that makes it the ideal choice for a variety of system reset applications. With its highly integrated features and wide input voltage range, it is suitable for use in a variety of power supply reset and power-on reset applications. The device is available in either a 8-pin DIP or 8-pin SOIC package, and is available in both a lead-free and leaded version.
