Power management integrated circuits (PMICs) are designed to meet the needs of complex, battery-powered systems. An essential part of any PMIC, Supervisors are used for on-chip and off-chip monitoring, system protection, and reset/power-on sequencing. As part of the Micrel’s portfolio of devices, the MAX700CSA family of Supervisors offers unique functions and capabilities, making them the ideal choice for a wide range of applications. This article will discuss the application field and working principle of the MAX700CSA to make it easier to understand the device and its potential uses.The MAX700CSA family of Supervisors is designed to monitor system supply voltages, provide system reset initiation and initiate power-on sequencing. The devices are available in a wide range of fixed-threshold voltages and can also be configured to provide an adjustable asserted-threshold voltage. In addition, the MAX700CSA family offers features such as brown-out protection, active-low and active-high RESET outputs, optional manual reset control input, and active-low MAXOK input.The MAX700CSA family is most commonly used in microcontroller-based systems. Other possible applications include PCs, laptops, consumer electronics, instrumentation, and industrial equipment. The MAX700CSA can also be used to monitor on-chip voltage supplies and provide supervisory functions for system memory and other on-chip components.The operation of the MAX700CSA is based on a voltage threshold being set at a specified level. If the connected supply voltage drops below this level for a predetermined period, the device will initiate a reset signal. The output RESET signal is kept active for a certain amount of time before the device releases it and allows the system to power-on again.For industrial applications, the MAX700CSA family of Supervisors is designed to provide precise control of reset and power-on sequencing. In addition to monitoring supply voltages and initiating reset, the devices are also capable of providing active-high or active-low RESET signals and controlling a manual reset input. The MAXOK input is used to monitor the status of other system components and provides an additional layer of safety by allowing the device to detect open circuit and short circuit conditions.In terms of power management solutions, the MAX700CSA family of Supervisors provides a reliable, cost-effective and configurable solution. With their range of features and options, these devices make it possible to implement a wide range of safety, monitoring and reset functions.In conclusion, the MAX700CSA family of Supervisors offers a wide range of features and options to meet the needs of microcontroller-based and other applications. The devices provide reliable reset and power-on sequencing and can be configured to provide active-low or active-high RESET signals as well as open circuit and short circuit monitoring. Described above, these features make the MAX700CSA devices an ideal choice for applications where precise control of reset and power-on sequencing is required.
