The MAX818LEPA+ is a low-power, precision supervisory circuit for monitoring system voltages and controlling system power-up reset. It is capable of seamlessly and accurately supervising a wide range of voltages in a variety of applications, including single and multiple supply sources, in automotive, consumer and industrial systems. It is one of the most versatile and reliable supervisors available, and is ideally suited for a variety of portable and critical voltage-monitoring applications.

The MAX818LEPA+ provides ultra-low power consumption coupled with tight regulation and fast response time. It features reducing user circuit complexity and eliminating the need for additional voltage monitoring regulators and separate reset logic, saving both cost and space. The MAX818LEPA+ is housed in a tiny, 1.6 mm x 1.3 mm, 8-pin, Thin QFN (TQFN) package, making it one of the most compact single-/dual-supply supervisors in the market.

The MAX818LEPA+ is a precision, dual-voltage supervisor with integrated logic and reset types. It provides reset output with maximum accuracy and response time and a reset factors of 20 μA, with both supply pins connected. The reset output is always active when the voltage at any of the input pins falls below the predetermined thresholds. It also provides protection against under-voltage as well as over-voltage conditions, with a threshold down to 0.8V for VCC and 0.4V for VBAT.

The MAX818LEPA+ is well suited for applications that require multiple power domains and power supply regulation. It typically is used to monitor and control power in automotive, consumer, and industrial systems, by detecting and responding to a wide range of supply voltages. It can be used in a wide range of applications such as automotive, consumer and industrial systems. MAX818LEPA+ can monitor multiple power domains as well as output a reset signal when one or more supply voltages fall below their predetermined threshold levels.

The MAX818LEPA+ monitors both high and low voltage conditions. Its programmable up and down voltage thresholds make it applicable for a variety of applications and supply/battery thresholds. It also has adjustable watchdog timeout and reset delay features, allowing for programmed reset events. These features make MAX818LEPA+ an ideal choice for power management applications requiring voltage supervision and reset control.

In order to provide the most accurate supervision, the MAX818LEPA+ has an integrated Schmitt-trigger hysteresis to eliminate false triggers due to noise. It also supports asynchronous reset with active-low and active-high reset polarity options. Its internal reset circuit eliminates the need for extra external components and reduces the size of the system-on- chip design.

The MAX818LEPA+ also features extended supply voltage range-2.7V to 5.5V, and up to 20 mA of operating current, making it suitable for applications requiring supply range of up to 45V. The integrated watchdog feature further helps reduce power consumption and increase the system’s efficiency. These features make the MAX818LEPA+ one of the most versatile and reliable supervisors for many demanding applications.

The MAX818LEPA+ is one of the most reliable and efficient precision supervisors available today. Its wide range of features and comprehensive feature set make it suitable for a wide range of applications in a variety of operating environments. The low operating current and tiny package also save power and size in portable applications. The MAX818LEPA+ makes it easy for users to implement accurate and reliable voltage monitoring, system reset control, and power-up reset in their applications, allowing for more efficient and reliable operations.
