The TPS3124J18DBVR is a PMIC or Power Management IC supervisor with a wide range of applications and use cases. This supervisor device is a Type 1 (1.8V to 5.0V) voltage supervisor with over-voltage protection, under-voltage protection, adjustable delay time and various reset indicator outputs. It supports both active-high and active-low logic outputs and is offered in a 10- pin VSSOP package. This device is designed to detect and monitor voltage levels in order to protect circuits from damage caused by voltage fluctuations or power outages. It provides a reset signal when the monitored voltage falls out-of-range, or when there is an excessive current draw or overload.

The TPS3124J18DBVR is used in a variety of applications, including power sequencing, brown-out detection, and power supply sequencing/monitoring in systems. This supervisor device can also be used as a reset generator and watchdog timer, ensuring that systems return to their default state if any type of unexpected event occurs. It can also be used to facilitate the safe shutdown of a system in the event of an out-of-range voltage. The TPS3124J18DBVR is suitable for both industrial and commercial applications including those found in internet of things (IoT) devices.

The TPS3124J18DBVR is able to support a wide range of voltages from 1.8V to 5.0V, making it suitable for most applications. It has an adjustable reset/delay time of 2.5ms to 10ms and the typical voltage accuracy is ±4.09%. This device has an active-high or active-low logic output, allowing for easy integration into any system. It also has a low quiescent current consumption of just 3µA, ensuring that it does not affect the power consumption of the system.

One of the main features of the TPS3124J18DBVR is its wide operating temperature range, from -40°C to +125°C. This allows it to operate in extreme temperatures and it also has a low shutdown current of 0.3µA, which ensures that the system stays in a low power state when the supervisory device is not in use. This feature makes the TPS3124J18DBVR ideal for battery operated devices and other low power applications.

The working principle behind the TPS3124J18DBVR is simple but effective. When the input voltage goes above or below the pre-set thresholds, this device will assert a reset signal, allowing systems to be returned to their default state in the event of a power outage or voltage fluctuations. This reset signal can be configured to be either active-low or active-high depending on the application. The output of the reset signal is then used to trigger an interrupt or event in the system to let it know that the monitored voltage has gone out of range.

The TPS3124J18DBVR is a useful power management tool for a range of applications, ideal for providing additional system protection in the event of a power outage or voltage fluctuation. Its ability to support a wide range of voltages and its adjustable delay time, combined with its low quiescent current consumption make it suitable for a variety of applications, both industrial and commercial. Whether used as a reset generator, a watchdog timer, or to facilitate a safe system shutdown, the TPS3124J18DBVR is the perfect choice for any power management solution.
