The TPS3513DR is a PMIC - Supervisors device in Texas Instruments\' PMIC product family. It provides integrated voltage supervision circuit, which continuously monitors up to two open-drain outputs, or one open drain and one push-pull output. This device is specifically designed in a very small package footprint and with low power consumption, perfect for powering LEDs, or other portable devices. The TPS3513DR is capable of operating accurately over a wide range of supply and temperature ranges, making it ideal for use in a wide variety of applications. In this article, we will dive into the application fields and working principles of the TPS3513DR.

The TPS3513DR is a high precision, low quiescent current voltage supervisor. It has an industrial operating temperature range of -40°C to +125°C and is capable of working with a wide supply voltage range of 2.2V to 25V. This ensures that the device can be used in a variety of applications and environments with consistent performance. The device contains two OVP comparators to monitor two externally adjustable voltage sources and two POR outputs, providing two output voltage trip points. The slop and reset time of both the upper and lower trip points can be adjusted by external capacitors, increasing system reliability and optimization. Furthermore, the TPS3513DR also contains an integrated power-on reset circuit which is capable of generating a reset signal when the system supply voltage is below a predetermined level.

The TPS3513DR works by continuously monitoring the input voltage levels at both the high and low voltage comparator inputs. When the input voltage goes below the lower trip point voltage (V_LOW), the OV_A output will be driven active low. Similarly, when the input voltage goes above the higher trip point voltage (V_HIGH), the OV_B output will be driven active low. The two outputs can be used to initiate safety events and or to provide supervisory cues. This device can also be employed in lighting applications, where it can be used to monitor the LED current and turn off the LEDs when the current reaches a particular level. This allows for a more efficient LED lighting system, as the LED lights can be powered off as soon as the current level reaches the desired level, thus saving energy.

The TPS3513DR is designed to be used in a variety of applications including consumer electronics, automotive, instrumentation, industrial and medical systems. This device can be used to provide system power fail indication in consumer electronics, such as portable music players and smart phones. Its small package footprint makes it ideal for tight spaces in consumer electronics. The device can also be used to monitor voltage levels in automotive systems, instrumentation and industrial systems, so that when the voltage level drops below a certain level, system power can be shut off, preventing damage to components or malfunctions. In medical applications, the TPS3513DR can be used to monitor the operating voltage of medical instruments, providing a reliable and accurate power off indication.

In summary, the TPS3513DR is a high precision, low quiescent current voltage supervisor device from Texas Instruments\' PMIC product family. It is ideal for use in a variety of applications due to its wide operating temperature range, low power consumption and small package size. The device is capable of monitoring two open drain outputs, or one open drain and one push-pull output, and providing two output voltage trip points. It can be used to detect system power failures in consumer electronics, automotive systems and instrumentation, as well as providing power off indication in medical systems. This device offers versatility and reliability in a wide variety of applications.
