PMIC (Power Management Integrated Circuit) supervisors are integrated circuits that monitor the power supply of an electronic system to ensure its safe operation. They have a variety of specific applications, depending on the type of circuit and the system they are used on. This article will discuss the application field and working principle of the TC32MEDB713, a PMIC supervisor from Texas Instruments.

The TC32MEDB713 is a PMIC supervisor designed for microcontrollers and DSPs. It offers 4 system power supply domains and a wide input voltage range from 2.54 to 5.25 volts, giving it greater flexibility when used with various microcontrollers and DSPs in automotive and industrial applications. It also has an input voltage monitor, an output voltage monitor, over-voltage and over-temperature protection, as well as low power sleep and wake functions. This makes it suitable for applications that require a high level of reliability.

The TC32MEDB713 is an especially suitable choice for automotive and industrial applications because of its high-temperature operation capability (up to 125ºC) and reliable protection features. Additionally, its current consumption is only 4µA, which makes it an ideal choice for applications where low power consumption is a priority. The device also offers a wide range of compensation options which allow users to optimize the system according to their specific needs.

The TC32MEDB713 is capable of providing robust protection for microcontrollers and DSPs. It monitors the supply voltages for over-voltage, under-voltage and over-temperature events and can also detect open load and short circuit conditions. In the event of a fault, the supervisor will power down the system and alert the user via an interrupt pin.

The TC32MEDB713 also has a variety of configurable protection levels, enabling the user to tailor the device’s behavior to the specific application. It supports both manual and automatic retry functions, allowing the user to configure the number of retries and timeouts before a system reset is executed. This allows the system to detect and recover from minor faults such as momentary power losses.

The TC32MEDB713’s operating principle is based on a combination of digital and analog components. It first monitors the system supply voltages via digital logic circuits. This data is then sent to an internal voltage supervisor which is responsible for performing the actual fault detection. Upon detection of an over-voltage, under-voltage, over-temperature, open load or short circuit fault, the supervisor will immediately trigger an interrupt and power down the system. This helps ensure the safe operation of the system in hazardous conditions.

In summary, the TC32MEDB713 is a PMIC supervisor which is designed specifically for automotive and industrial applications. It offers a variety of protection features and configurable options which allow users to tailor the system’s performance to their specific needs. Additionally, it offers low power consumption, high temperature operation and reliable protection, making it an ideal choice for a wide range of applications.
