BU4916F-TR

Introduction

BU4916F-TR is an advanced, low power, highly integrated monolithic PMIC-Supervisors. The device is powered by a 3.3V supply and is available in either a Tri-State or Quad-State configuration. It features a watchdog timer, reset generator, power-on reset and voltage monitor, power-good input/output, and a software reset. The device can be used for a wide range of applications, including system monitoring and control, industrial process control and embedded systems.

Applications

The BU4916F-TR is suitable for a variety of applications, including system monitoring and control, industrial process control and embedded systems. In embedded systems, it is often used as a reset controller, power-on reset, or real-time clock supervisor. It can also be used in systems requiring multiple, simultaneous power-ups.

The BU4916F-TR is capable of providing a low-voltage output, allowing it to continue to reset the system even when the main power supply fails. It can also be used to control the reset of a system in response to different levels of voltage and/or temperature. This is especially important in industrial applications, where safety is of the utmost importance.

Working Principle

The BU4916F-TR monitors the voltage and temperature of the system and provides an assertion to the system reset line when the voltage or temperature is beyond the preset limits. It contains multiple registers to set the thresholds for detection, allowing for customised fault protection. The voltage monitor can detect a range from 2.5V to 6V and can be configured to activate a reset when at either the upper or lower thresholds. Temperature monitoring is designed to protect the system from extreme operating temperature conditions.

The BU4916F-TR contains a hardware reset generator, which can be enabled either manually or through the set-up registers. This can be used as a failsafe reset, as it will activate even when the voltage monitor fails. The watchdog timer is capable of resetting the system every two seconds, 40 seconds, two minutes or 10 minutes, depending on the set-up registers. The power-on reset is a power-on reset meant to initialise the system when power is applied to the device. Finally, the software reset is designed to allow software to have control of the reset line, to reset the system in response to software events.

Conclusion

The BU4916F-TR is an advanced, low power, highly integrated monolithic PMIC-Supervisors, suitable for a variety of applications. With its wide range of features, including a watchdog timer, reset generator, power-on reset, voltage monitor, power-good input/output and software reset, the BU4916F-TR can provide reliable system monitoring and control.
