Overview

TPS3852G33QDRBRQ1 is a member of the TPS385x family of precision supervisor devices. It is mainly used for power management and control applications. The device provides the system designer with a comprehensive monitoring, reset and voltage supervisor in one highly flexible solution. As a supervisor, TPS3852G33QDRBRQ1 is designed to monitor multiple levels of power by monitoring supply voltages and multiple independent I/O signals in order to determine the correct operating state of the system.

Application Field

TPS3852G33QDRBRQ1 is targeted for use in a variety of consumer, computing and industrial applications. It can also be used in communication, data acquisition, and other applications needing reset and supply voltage supervision, such as system power monitoring and data storage, to ensure more reliable operation.For consumer applications, TPS3852G33QDRBRQ1 is compatible with Intel Processors with 1.8 V and 3.3 V bias rails and is an ideal choice for power management and reset controller functions. This device is applicable for digital cameras, PDAs, MP3 players and other consumer devices.In computing applications, this device is used mainly for supply monitoring and fault reset operation. It is also applicable as an alarm reset controller and/or system power monitor in server systems.For industrial applications, the device can be used to provide monitored supply voltages and generate reset over-voltage warnings.

Working Principle

TPS3852G33QDRBRQ1 works by monitoring the status of various external conditions and signals. The input signals can be detected by the device, depending on the application. These conditions can be power failure, over-voltage and under-voltage conditions, logic levels, current levels and temperatures.Depending on the user-defined operation modes, the device will generate an appropriate reset duration, which can be configured with a range of time-out facilities.In addition to using the external voltage, current and temperature inputs to activate the reset, TPS3852G33QDRBRQ1 can also be used to detect fault conditions and/or react to external logic inputs or current levels.If a fault condition is detected or an external logic or current request is received, the device will generate a reset pulse of user-defined duration, or it can activate the system’s power-on reset controller.The device also offers the user a wide variety of operating modes which, when customized and combined, provide extensive flexibility for reset and voltage supervision.

Conclusion

In conclusion, TPS3852G33QDRBRQ1 is a highly flexible device which is suitable for multiple application fields such as consumer, computing and industrial applications. Through its unique combination of features and functions, this device is able to provide designer with comprehensive monitoring, reset and voltage supervision to ensure reliable operation.
