Power management integrated circuit (PMIC) is one of the most important components in any electronic device. It is designed to provide efficient and reliable power management solutions in a wide array of applications. One of the most popular PMICs is the TPS3779BDRYT, which is commonly used in handheld electronics devices such as mobile phones and portable media players. TPS3779BDRYT is a PMIC supervisor which provides system power protection with low power consumption. The main function of TPS3779BDRYT is to help ensure that the system obtains reliable power supply within a voltage range from 1.8V to 5.5V. It provides four overvoltage protection thresholds, two brownout/undervoltage protection thresholds, and one smart soft-start timer. All this is achieved in a single chip that is just 0.38mm² in size.TPS3779BDRYT is a flexible system power supply supervisor IC that provides an enhanced level of protection features and improved system performance. It is equipped with an internal oscillator to reduce the external components count, four over voltage thresholds, two brown-outs, and one soft start timer. This ensures that the system receives reliable power supply, maintained by the internal oscillator and over voltage protection from 1.8V up to 5.5V. TPS3779BDRYT can be configured for two distinct operating modes; input edge-based mode and pulse-accumulation mode. In edge-based mode, the IC monitors the input voltage and starts the reset timer when the voltage drops below the lower threshold. Once the timer expires, an active low reset signal is asserted. In pulse-accumulation mode, the device will continuously monitor the input voltage and accumulate the number of low voltage pulses. After a certain number of low voltage pulses is accumulated, an active low reset signal is asserted.

TPS3779BDRYT’s reset signal can be used to monitor the different types of system fault such as voltage drop, brownout, overvoltage, and system lockup. This reset signal can be used to reset various components such as system microcontroller, microcomputer, memories, and application specific ICs (ASICs). This reset feature can also be used to safe guard the system in the event of a system fault, ensuring proper operation and protection of the system. In addition, TPS3779BDRYT can be used for system diagnostics, like testing for system power supply failure or low voltage conditions.

TPS3779BDRYT is a highly efficient PMIC supervisor IC and has become a popular choice for handheld devices due to its size, low power consumption, and ability to provide excellent protection against system faults. Its multiple protection and reset features also provide additional protection for the device, making it a reliable and cost-effective solution for mobile and portable systems.
