Introduction to MAX821RUS+T

MAXIM Integrated MAX821RUS+T is an integrated, low-power and space-efficient supervisor IC that is specifically designed for system operational, processor, and power supply monitoring. The MAX821RUS+T features a simple reset circuit with adjustable low-voltage reset, power-on reset (POR) and reset pulse output. Additionally, it provides a delay timer circuit with adjustable timeout to debounce the power-on transitions. As part of the MAX821RUS+T family, MAXIM Integrated provides a premium combination of the popular MAX821 with the temperature-rated MAX851T supervisor ICs, available in thermally enhanced packages that dissipate 2.9W (14.85mm2). These ICs are ideal for applications where space is at a premium and long-term reliability is a top priority.The various MAX821RUS+T families include both extended current-monitoring and low-voltage supervision features, with optional connection to a host processor that is capable of measuring the temperature, output current and system power-on time. In addition, there are four different families of MAX821RUS+T, with each providing a unique combination of features and performance in terms of reset output types, low voltage reset thresholds and other features.

Application Field & Working Principle of MAX821RUS+T

MAX821RUS+T is a power management IC that is designed for use in a variety of application, including low-power systems, SoC (System on Chip) designs and in embedded systems. The MAX821RUS+T supervises the power supply voltage (VCC), monitors and maintains system power-on time (tpor) and offers adjustable low voltage reset thresholds. The MAX821RUS+T is also equipped with a temperature-rated MAX851T supervisor, allowing for temperature and humidity monitoring and control. The MAX821RUS+T can be configured to generate several different reset signals, including an active-low reset, active-high reset, active-low and active-high open-drain reset and a power-on reset. Moreover, it offers adjustable timeout period (ttime) and delay timer (tpor) with adjustable cycle period. The MAX821RUS+T also features a unique dual-input voltage supervisor circuit to ensure reliable system power-up. The MAX821RUS+T is typically used to monitor and maintain system power-on time (tpor), and offers adjustable low voltage reset thresholds and adjustable two sequential reset signals to ensure reliable system startup. Additionally, the MAX821RUS+T is equipped with a temperature-rated MAX851T supervisor, allowing for temperature and humidity monitoring and control. Furthermore, the MAX821RUS+T can be configured to generate several different reset signals, including an active-low reset, active-high reset, active-low and active-high open-drain reset and a power-on reset. Additionally, it offers adjustable timeout period (ttime) and delay timer (tpor) with adjustable cycle period.
