PMIC Supervisors play a critical role in the semiconductor world, providing voltage monitoring, reset, and a host of other functions. The MAX16060ETE+ is a robust, high-performance PMIC supervisor that combines a voltage level detector and reset interface for automotive, industrial, and commercial applications. This article explores the application field and working principle of the MAX16060ETE+.

The MAX16060ETE+ is designed for monitoring system voltages and assisting with power-on reset (POR) for a variety of embedded systems. It assists in the initial startup, power sequencing, and other management operations that ensure a system\'s continued operational life. By accurately sensing system voltage levels, it can also dramatically improve system reliability, reduce electro-magnetic interference (EMI), and increase efficiency.

The MAX16060ETE+ is well-suited for potential automotive applications, judging by its extended environmental/temperature range (-40°C to +125°C operating temperature, -55°C to +160°C maximum junction security, and AEC-Q100 qualification). Automotive-grade inductors and capacitors, as well as a low total harmonic distortion (THD) level of 0.12%, enable successful integration into automotive power management systems. The device also supports a wide variety input voltages and common POR levels.

Additional benefits offered by the MAX16060ETE+ include an 8-bit I2C interface, predictable POR time delay, programmable output debounce time, and low-power consumption (1.1mA typical operating for current). All these features simplify development and installation, provide greater communication platform flexibility, and ensure fast and reliable power-on reset capabilities.

Functional Working Principle

The MAX16060ETE+ features a configurable voltage level detector (VLD) that provides simple voltage monitoring and brings about system reset when the voltage dips below a specified level (typically the 2.97-3.3V range). The device can be programmed to monitor a range of voltages, responding with a low output when the input dips below the set threshold. This allows developers to quickly adjust the device to work with a variety of input voltages, while also avoiding costly hardware changes.

When the VLD input voltage dips below the set threshold, the MAX16060ETE+ outputs a reset signal that is used to reset system components. This reset sequence typically begins with the lowest risk components (power-supply components) and works upward, eventually targeting the CPU after power-supply levels stabilize. This reset sequence can be programmed and is typically timed to guarantee system reset within a few milliseconds.

The MAX16060ETE+ is also highly configurable. Its 8-bit I2C interface allows for simplified programming and control, while also enabling various system configuration options (such as the frequency the voltage is monitored). This programmability, in combination with its extended temperature range, make the device well-suited for many critical, high-temperature monitoring applications.

Conclusion

The MAX16060ETE+ supervisory circuit is a powerful and highly configurable device that provides critical voltage monitoring and reset capabilities when properly applied. For automotive, industrial, and commercial applications, the MAX16060ETE+ is a great choice for ensuring system reliability, reducing EMI, and efficiently managing power-on reset operations.
