The TPS3824-25DBVR is a low-voltage reset supervisor. It monitors a single supply voltage, typically 3.3V, and generates a reset signal if the voltage drops below an adjustable threshold level. The TPS3824-25DBVR is a standard voltage supervisor, with an adjustable reset threshold, manual reset, and push/pull reset outputs. The device also has an output-delay selection that can be used to prevent a false reset from fast transients in noisy power systems. The TPS3824-25DBVR is packaged in a small 8-pin or 6-pin SOIC.

Applications for TPS3824-25DBVR

The TPS3824-25DBVR is commonly used in a wide range of applications including PC motherboards and servers, networking, communications, and industrial control systems. It is also used in embedded systems and automotive, medical, and aerospace applications. The TPS3824-25DBVR can be used to monitor supply voltage levels and provide system reset in case of power supply failure or brownout conditions. It can also be used to detect overvoltages, undervoltages, manual reset, and push/pull reset events.

Working Principle of TPS3824-25DBVR

The TPS3824-25DBVR operates by detecting the voltage of the monitored supply. If the voltage falls below an adjustable threshold, then a reset signal is generated. The TPS3824-25DBVR has an adjustable reset threshold, adjustable output delay, manual reset, and push/pull reset outputs. It is packaged in an 8-pin or 6-pin SOIC.

When the monitored voltage drops below the reset threshold, the TPS3824-25DBVR initiates a reset signal. The reset signal is active low and remains asserted until the monitored voltage rises above the reset threshold. The duration of the reset pulse is adjustable and can be selected to accommodate different system requirements. The manual reset input is also active low and is used to initiate a reset pulse when asserted. The push/pull reset output is active low, and is used to control external reset components. The TPS3824-25DBVR also features an output delay selection, which can be used to prevent false resets from fast transients in noisy power systems.

Conclusion

The TPS3824-25DBVR is a low-voltage reset supervisor used in a wide range of applications. It monitors a single supply voltage and generates a reset signal if the voltage drops below an adjustable threshold level. The device features an adjustable reset threshold, adjustable output delay, manual reset, and push/pull reset outputs. The output-delay selection can be used to prevent false resets from fast transients in noisy power systems. The TPS3824-25DBVR is packaged in an 8-pin or 6-pin SOIC package.
