PMIC - Supervisors

PMIC (power management integrated circuits) are the most essential component in any electronic device. Supervisors are a specific type of PMIC that are used to monitor the power supply of the system, regulate the system power, and protect the circuit from overvoltage and high temperature. The TPS3836H30DBVR is a voltage supervisor. It consists of an ultra-low-power comparator and an adjustable reset delay counter along with a 4.5V to 5.5V voltage regulator.

Application Field

The TPS3836H30DBVR is designed to monitor a system\'s power supply, or supply voltage. It can be used in a wide range of applications, from servers to smartphones, wearables to gaming consoles, and from automotive systems to home appliances. With its low standby current, this device can also be used in battery-powered applications, too. Additionally, the TPS3836H30DBVR features a wide operating temperature range of -40°C to +125°C, making it suitable for use in extreme temperatures.

Working Principle

The TPS3836H30DBVR is an ultra-low-power comparator designed to monitor a system\'s power voltage. When the voltage drops below the preset threshold, the device triggers a reset and generates an output signal. This reset signal can be used to reset the system, alert the user, and protect the device from the effects of unfavorable conditions, such as power outages. The device also features an adjustable reset delay counter, which determines the duration of the reset signal.

In order to operate seamlessly, the TPS3836H30DBVR also incorporates a 4.5 to 5.5V voltage regulator. This regulator ensures that the supply voltage of the supervisor does not exceed the maximum level and helps maintain a stable voltage output. The device also includes an over-temperature input, which triggers the reset signal when the temperature exceeds the preset threshold. The TPS3836H30DBVR also has open-drain outputs, which provide a low voltage-level reset signal.

Having this device in a system ensures a reliable power supply, protection from power and temperature fluctuations, and helps preserve power consumption in battery-operated systems. As a result, the device can significantly extend the life of a system, increase reliability, and reduce system downtime.

The TPS3836H30DBVR is a versatile and reliable voltage supervisor, and its wide application range makes it a perfect fit for many different systems and devices, from small consumer electronics to large industrial systems.
