Power management integrated circuits (PMICs) are a type of integrated circuit that are used to regulate and manage the supply of power in order to maintain the electrical and thermal performance of the system in which they are used. PMICs are a major part of any power system design, providing the necessary control for power supply, load current, and output voltage. A key function of PMICs is to protect against various electrical and thermal faults in order to ensure that the system remains stable in operation. One of the most widely used PMICs is the BD4935FVE-TR, widely used in a wide variety of applications.

The BD4935FVE-TR is a Programmable Reset Supervisory IC designed for reset generation and power supply monitor functions. It features output voltage selection from 1.5V to 3.3V, LED control, windowed watchdogs, system power-on reset (POR), brown-out detect (BOD) and power-fail detect (PFD) circuits. This device is ideal for use in applications such as computers, laptops, home appliances and medical diagnostic instruments.

The BD4935FVE-TR works by monitoring the input voltage applied to the device through a voltage sense circuit. When the voltage is above or below the predetermined thresholds, the chip will issue a reset. The reset can be detected by the host processor through a RESET# pin, allowing the host processor to perform its power fail and memory check processes. The device also features a programmable voltage threshold and reset time delay, allowing the system designer to customize the reset characteristics for their specific application needs. In addition, the device can be used in conjunction with a watchdog timer to provide additional safety measures.

The BD4935FVE-TR is a low-power, low-cost solution to provide reset functionality in a multitude of applications. The programmable reset thresholds, reset time delay and LED control make it an attractive choice for designers looking to optimize their system’s power and reset management. It is important to note that while the BD4935FVE-TR is a very good device, care should be taken to ensure that the reset functionalities of the device meet the requirements of the system in question.

The BD4935FVE-TR is a versatile device and can be used in a wide range of scenarios where reset generation and power supply monitoring is required. It is particularly useful in embedded system applications where space, power and reset management are key considerations. It can also be used in industrial systems, computer and consumer electronics applications, where robust reset and power monitoring features are needed. Regardless of the application, the BD4935FVE-TR can provide reliable and effective reset functions.
