MAX8213AESE+

The MAX8213AESE+ is a supervisor integrated circuit that provides an optimal balance between system cost and complexity. It is designed for increasing the reliability and performance of various digital applications such as power supplies, audio amplifiers, digital controllers, and communications systems. This supervisor provides regulated and adjustable RESET and supply rails that help ensure reliable operation of any electronics system.

The MAX8213AESE+ supports voltage inputs ranging from 2.6V up to 13.2V and is available in a variety of packages, ranging from a small and versatile 5-pin TSOT-23 to a larger and more robust 8-pin SOIC. Its built-in fault protection features include over-temperature shutdown, voltage overvoltage protection, output short circuit protection and thermal overload protection, allowing it to operate in a variety of hostile environments and conditions.

The MAX8213AESE+ integrates two reset outputs, a voltage monitor output, an adjustable low battery detect output, and a manual reset input. Both RESET outputs are active-high, RESET1 is active-low, and the voltage monitor output is active-low. The adjustable low battery detect feature can be set to monitor voltages below 2.6V, making the MAX8213AESE+ ideal for lithium ion battery-powered applications. The low battery has a fault interrupt (FI) pin, which can be connected to a system interrupt to trigger a reset.

The supervisor\'s two adjustable output rails are designed to supply regulated voltages as CLK and RESET signals with no bus-load or current surge. The CLK output is a voltage-controlled current source and is capable of supplying up to 0.5mA at a maximum of 4.5V. The RESET output, on the other hand, is designed to operate in the environment where power cycling is expected, and is capable of driving up to an internal virtual ground, allowing the supervisor to sense a soft start by itself. Finally, the supervisor supports both supply and ground monitoring, enabling it to detect any unexpected overvoltage or undervoltage conditions.

The MAX8213AESE+ supervisor utilizes a failure detect/acknowledge protocol, which ensures that reset pulses exceed the minimum reset time and that the supervisor will not attempt to complete a reset sequence until all of the supervisor\'s supply rails have stabilized. The supervisor also supports manual reset, allowing the user to reset the system by a simple act of pressing a button or delaying a reset signal until all of the supervisor\'s supply rails have stabilized.

The MAX8213AESE+ is an ideal choice for powering digital applications that require reliability and robustness as well as active protection mechanisms. Its adjustable voltage output rails provide the necessary power for digital controllers, audio amplifiers, and communications systems, while its manual reset input ensures system reliability and fault protection. Its integrated fault protection features enable the MAX8213AESE+ to operate safely and reliably in a variety of hostile environments and conditions.
