The TPS3850H50DRCR is a type of supervisor found within power management integrated circuits (PMICs), designed to provide system monitoring and protection features as well as providing power. Through its different applications, the device is able to allow advanced applications of power management, while being constrained by the same amount of used components. This article will be looking at the typical application field of the TPS3850H50DRCR and the working principle behind it.
The application field of the TPS3850H50DRCR PMIC supervisor is specifically aimed at devices used for controlling digital power applications, such as microprocessor systems, voltage regulators and power converters. The supervisor is designed to be integrated into digital power supplies and controllers and to provide a wide range of protection, including multi-rail voltage monitoring, too high/low voltage detect, over current detection, as well as temperature monitoring. Typical applications include portable electronic and computer related devices, but it can also be used wherever there’s a need for voltage and temperature monitoring and protected control.
The main working principle behind the TPS3850H50DRCR device is to sift through the different inputs it receives and output the results accordingly. It is a voltage-detecting supervisor IC powered by a single supply voltage, with a wide range of voltage levels to be detected. It allows users to set different operating voltages, which are compared to the voltage level of the input signal. Depending on the set level, the output will turn on when the input voltage level reaches or surpasses the set level. On the other hand, the output will turn off when the input voltage level drops below the set level. The voltage detection level is factory preset for 1.60V and 5.50V, with programmable hysteresis to prevent noisy false detections. It is also able to detect both overvoltage and undervoltage warnings.
The device can also be used to detect overcurrent conditions, with a preset trip point of 1.5A and an adjustable threshold of 0.5-2A in intervals of 0.5A. Furthermore, another type of protection the device provides is temperature protection, with a preset temperature threshold of 170C. This way, the TPS3850H50DRCR is widely used in power units and systems, being able to act as a system watchdog and provide over-temperature protection and overclocking prevention. Additionally, it has adjustable output active pull up and pull down resistors which can be used to improve low level driven compatibility, as well as adjustable voltage limits.
Overall, this sense-and-control supervisor IC allows reliable protection and monitoring of digital power systems, providing protection against overvoltage and undervoltage conditions, as well as against over-temperature and overcurrent conditions. Additionally, it offers users the ability to set operating voltages and temperatures, as well as adjustable output active pull up and pull down resistors, enabling compatibility with a wide variety of digital power supplies. The device is highly recommended due to its different capabilities and potential applications.
