PMIC - Supervisors — TPS3836H30DBVRG4 Application Field and Working PrinciplePMIC, or Power Management Integrated Circuits, is an integrated circuit used to manage power in electronic devices and systems. They have become an essential part of modern electronics, with more and more integrated circuits being specifically designed for power management. One such family of PMICs is the supervisors. This article will focus on TPS3836H30DBVRG4, an application specific supervisor and discuss its application field and working principle.The TPS3836H30DBVRG4 is an adjustable series of Active-High, Active-Low and combined reset devices. It is used as a reset supervisor in consumer, industrial, medical and automotive systems. It is designed to provide protection against brown-outs, spikes, and overvoltage conditions, as well as protect against lock out during power up sequencing. It also provides over-temperature protection as well as low power consumption in both standby and normal modes. This makes it ideal for use in battery powered applications.The TPS3836H30DBVRG4 features three inputs and a single output. The three inputs are Power Supply Voltage, Activity Request and Supply Request. These inputs are monitored and compared with the reference voltage and, when the user-defined conditions are met, the output is asserted. The output is a logic level signal that indicates the current power state of the device. This signal is then routed to the microcontroller to enter or stay in suspend mode.The TPS3836H30DBVRG4 supervisor operates by monitoring the input power supply voltage and Activity Request signals. The Activity Request is used to indicate to the supervisor when the device is active and when it is not active. This signal allows the PMIC to control the power consumption of the device. The Supply Request signal is used to indicate to the supervisor when the device is in need of power. This signal allows the PMIC to engage standby power when needed. The Power Supply Voltage input is used to compare the voltage against a reference voltage and determine when the device is within operating parameters.Once the conditions have been met, the output signal is asserted to indicate that the device is ready to enter or stay in suspend mode. The TPS3836H30DBVRG4 supervisor is designed to reset and restart the device when the power conditions are met or when the Activity Request signal is asserted. The device also offers an adjustable timeout, programmable reset asserted level, and adjustable voltage window.The TPS3836H30DBVRG4 supervisor is designed to provide protection against overvoltage, undervoltage, and brownouts. It is capable of resetting or restarting the device when the power conditions are met. The TPS3836H30DBVRG4 also provides adjustable timeout, programmable reset assert level and adjustable voltage window. It is ideal for use in battery powered applications, given its low power consumption in both normal and standby modes.
