TPS3780BDBVT is a programmable on-board reset supervisor integrated circuit (IC). It serves to monitor and supervise voltage levels and currents in electronic devices, such as mobile phones, laptops, and tablets. This IC contributes to improved safety and reliability of the product by helping the device avoid reset problems and failure. This device was designed to be used in Class B and Class A applications, and is an essential part of any product operating in these application fields.

The TPS3780BDBVT IC has an operating temperature range of -40 to +125 ℃, and supports input voltage of 1.9 to 5.5 V. It has a low quiescent current range and low output voltage threshold of 0.90 V, allowing it to monitor and reset a wide range of voltages. The IC also has a high input impedance feature that can help protect the input voltage lines, as well as enable a single low-cost solution for monitoring a range of power sources.

The TPS3780BDBVT IC is an ideal reset supervisor for applications operating in Class B and Class A environments. It has an ultra-reliable edge detection functionality that is capable of detecting and triggering a reset application within 6 μs, making the circuit highly responsive and reliable. Moreover, the IC features a hardware reset output which can be used to reset external system components upon reset assertion. Furthermore, the IC has additional features for diagnostics, such as a precision voltage detector and a powergood indicator.

The TPS3780BDBVT IC also has built-in protection features including brown-out detection and over-temperature protection. It is also capable of protecting itself from false triggering due to ESD through its advanced ESD protection circuitry. This provides enhanced levels of immunity against false reset operation.

The working principle of the TPS3780BDBVT IC is quite simple. When the supervisor is powered up, the input voltage is compared to the voltage thresholds set in the IC. If the input voltage passes the thresholds, the IC assumes that the charge protocol is complete and will generate a control signal for the reset circuit. This control signal will initiate a reset cycle by resetting all of the components in the circuit and then turning the power back on.

Once the reset cycle is complete, the IC will then monitor the input voltage continuously and will generate another control signal if the input voltage exceeds the set thresholds. This control signal will again initiate a reset cycle, keeping the circuit operating reliably and safely. Additionally, the IC also has a timer which can be used to program the length of the reset cycle, allowing the IC to reset the circuit after a certain amount of time.

The TPS3780BDBVT IC is an ideal reset supervisor for a variety of applications operating in Class B and Class A environments due to its reliable edge detection, precision voltage detection, and integrated protection features. Its ultra-low quiescent current and adjustable reset cycle times make the TPS3780BDBVT IC an ideal choice for any application requiring a reliable and efficient on-board reset supervisor.
