The BD45292G-TR is a supervisor designed for various power systems. It comes with complete protection and monitoring circuits, ideal for micro-controllers, FPGAs, processors, etc. Originally manufactured by ROHM Semiconductor,BD45292G-TR is reliable, highly efficient and user-friendly. Also known as system manager, Supervisor IC is pre-configured and used to protect sensitive circuits against accidental over-voltage, current limiting, reverse voltage and output stability problems.

Applications

The BD45292G-TR is widely used in power management applications such as automotive systems, telecommunications, industrial and medical equipment. In telecommunication, for instance, it provides tight power supply control for RF/analog transmitters, receivers, as well as other communication equipment. In the automotive sector, it supports the on-board charging and power regulation for autonomous systems.

Working Principle

The BD45292G-TR is an integrated power management circuit with specialized protection circuits. It acts as a system manager and monitor, overseeing changes in the power supply and maintaining safe operating conditions. With a built-in Voltage Regulator (VR), the BD45292G-TR is capable of maintaining output voltage stability even when the input voltage fluctuates. It also features an inrush limiting circuit that prevents it from damaging heavy capacitance at the beginning of its power supply.

The BD45292G-TR also features over-current, thermal and reverse voltage protections to ensure that powered components are not damaged or affected by high or low voltages. When one of these protections is triggered, the supervisor cuts off the power supply, isolating the circuits from further damage. It also monitors short circuit and brown-out conditions, ensuring that the correct voltages are supplied to the system.

To provide reliable protection and monitoring, the BD45292G-TR has what is known as a keeper circuit. This circuit is able to continuously monitor external signals and make sure that they are within the expected ranges. If they are not, the keeper circuit will quickly take action, disabling the power circuit and alerting the user.

The BD45292G-TR is a multi-purpose system manager with excellent protection and monitoring capabilities that allows users to easily and reliably control external systems. With its pre-programmed protection and monitoring settings, it eliminates the need for users to manually set each parameter. This makes it ideal for power management applications where power supply reliability is paramount.
