The BD4837FVE-TR is an advanced system monitor IC that was designed and manufactured by ROHM Semiconductor. It consists of 8-channel regulated voltage monitor circuits and provides a high level of system reliability by constantly monitoring and controlling multiple power supply voltages. This IC is used in a wide variety of applications, ranging from consumer electronics to automotive applications. This article will discuss the application fields and working principles of the BD4837FVE-TR.

Application Fields

The BD4837FVE-TR IC is designed primarily for use in consumer and automotive systems, where it provides various applications and functions. For example, it can be used to monitor and control lithium-ion batteries found in mobile devices, as well as monitor car power supply and other voltages. It can also be used to monitor critical system voltages for events such as system reboot or thermal runaway. Additionally, the IC is also suitable for monitoring external switches, such as reset switches.

The BD4837FVE-TR is also suitable for monitoring various types of supercapacitors, such as nickel-zinc or lead-acid supercapacitors. The IC can provide precise monitoring of charge and discharge of the supercapacitors. This makes it an ideal choice for systems that require information about the state of a supercapacitor, such as those used in automotive powertrain applications.

Working Principle

The primary function of the BD4837FVE-TR is to provide high-precision voltage monitoring for a wide range of applications. The IC operates by monitoring the voltage of a system, and if the voltage drops or rises to an unsafe level, the IC will then provide a signal to alert the user of the threat. The IC can monitor up to eight different regulated voltages, and is capable of monitoring voltages ranging from 1V to 15V. Additionally, the IC can be set to provide over-voltage, under-voltage and over-current protection.

The BD4837FVE-TR also features a watchdog timer, which can be programmed to provide an alert if the system has not been reset after a predetermined amount of time. This feature is especially useful in preventing system hang-ups, which can cause the system to become unresponsive or crash. The watchdog timer can also be used to detect fault conditions and alert the system of a problem.

Finally, the BD4837FVE-TR comes with a range of sophisticated protection features that can help ensure the highest level of system reliability. These include over-temperature protection, leak current protection, and ESD protection. Additionally, the IC also has an OTP functionality, which can be used to provide additional security for the system.

Conclusion

The BD4837FVE-TR is an advanced system monitor IC that was designed and manufactured by ROHM Semiconductor. It is primarily used in consumer and automotive applications, where it can provide precise voltage monitoring and protection. It is capable of monitoring voltages ranging from 1V to 15V, and features a watchdog timer, over-temperature protection and leak current protection. The BD4837FVE-TR is an ideal choice for systems that require advanced protection features and high levels of system reliability.
