Power management integrated circuit (PMIC) is an important class of integrated circuits in today’s high-performance digital system. Supervisors form a major subcategory of PMICs, and they are used to monitor the voltage and current levels within the system. They are usually associated with reset tags, error messages, and similar types of alarms. The MAX690RCSA+ is a supervisor that performs all these jobs and more. It is a multi-channel voltage monitor and regulator designed for high accuracy and high speed operation. This article will discuss the application field and working principle of the MAX690RCSA+.
The MAX690RCSA+ can monitor voltage levels ranging from 4.6 to 5.5V and current states ranging from 1.2 to 4.0V. It has two different thresholds that can be used to set trip points; one set at the rising edge and one set at the falling edge. Additionally, it has adjustable timeout and reset delay periods, which can be used to adjust the duration of the low-voltage warning and the reset time in respect to the threshold levels. The input and reset logic levels can be individually configured as either high- or low-signal. With all these features, the MAX690RCSA+ can be applied to numerous scenarios, including embedded systems, computer peripherals, and automotive applications.
Apart from its physical specifications, the MAX690RCSA+ has an internal voltage monitoring function, which enables it to accurately predict and detect overvoltage and low-voltage conditions. Additionally, it can detect power transients such as voltage spikes, power supply brownouts, and similar anomalies, which can be used to prevent damage to the system. The MAX690RCSA+ also features built-in hysteresis and a power-on reset circuit.
The internal circuitry of the MAX690RCSA+ can be divided into two categories: the internal routing circuitry and the logic circuitry. The routing circuitry includes the internal pins that are connected to the external supply pins, and the logic circuitry includes the logic gates inside the chip. The different parts of the MAX690RCSA+ are connected together through metal layer interconnects and potential isolators. The logic gates are responsible for monitoring voltage levels, switching pins, and triggering a reset tag when needed.
The metal layer interconnects act as pathways for current to travel from one component to another. The potential isolators are used to prevent leakage currents from traveling between components, which would otherwise damage the device. The logic gates control the voltage monitoring and reset logic. The output pins are open drain, which makes it easier for them to be connected to other components without external resistors. The voltage monitoring circuit automatically detects low-voltage and overvoltage conditions and triggers a reset when appropriate.
The MAX690RCSA+ is an invaluable component for any power management system. Its versatile design and numerous features make it suitable for many applications, ranging from computer peripherals to automotive systems. The built-in voltage monitoring and reset logic guarantee fast and accurate detection of power faults and other anomalies. With its simple, stable circuitry, the MAX690RCSA+ is the ideal solution for a variety of high-performance digital system designs.
