Modern electronic devices have many different functions and feature sets, all of which typically require a mix of voltage rails and power sources to support their operation. As such, it is important to ensure that electronic devices are supplied with the correct and stable voltage levels, as well as to protect them from poor or unstable power supply and from potential faults or unexpected power outages. This is where PMIC (Power Management Integrated Circuits) Supervisors come in. PMIC supervisors are special power management integrated circuits designed to supply a stable voltage rail to the system and to provide protection against the threat of excessive current, overvoltage, undervoltage, and temperature. PMICs supervisors typically come in two varieties: general-purpose supervisors, and device-specific supervisors. The MIC706RM-TR is an example of a device-specific PMIC supervisor, specifically designed as a battery supervisor for 5-series/7-series/9-series microcontrollers, as well as various FPGA devices, such as the 100T, 200T, 400T and 500T families. The MIC706RM-TR is a fully-integrated solution that helps to optimize the MCU’s performance and accuracy under varying power conditions. It is a complete monitoring and protection solution for both the VDD and VBAT voltage rails of a microcontroller or FPGA device. It features a tiny form factor – measuring just 1.6 x 2.5 mm – and an operating temperature range of -30 to +85 degrees Celsius. The MIC706RM-TR offers a range of features to maintain the health and stabililty of the system, including an adjustable over-voltage and under-voltage supervisory circuit, as well as integrated temperature and battery voltage sensors, to provide over-temperature protection. It also includes a battery-stabilization stage to ensure the accuracy of the battery voltage, as well as a low-voltage reset circuit and an in-system programming support. The MIC706RM-TR’s primary function is to monitor and protect the VDD and VBAT voltage rails. It monitors the voltage levels of the power rails and then provides an interrupt signal to alert the system in case of an abnormal voltage level, or an over-temperature condition. The interrupt signal is used to take appropriate action, such as triggering a system reset or disablement of critical components. The MIC706RM-TR can also be used to control the system’s power consumption by responding to system power-mode changes, such as when switching from a run mode to a sleep mode. The MIC706RM-TR also features a programmable reset time-delay circuit, which is used to generate a reset signal to the connected system, when the input power supply is out of range. Furthermore, its I2C serial interface can be used to program its internal registers, allowing for further customization of its operation. In summary, the MIC706RM-TR is a device-specific PMIC supervisor that is designed to provide a reliable, integrated solution for a host of power-management and protection needs. Its advanced features, such as its temperature and battery voltage sensors, make it an ideal choice for a range of applications, such as MCUs and FPGAs, and it is available in a very small form factor to help reduce board space and cost.
