Analog devices’ TPS3123G15DBVT is a low-power supervisor IC that is used to reset a system on power spikes or as a result of a cascading reset. It is primarily used in computer, consumer and industrial applications where low power than the other supervisors is required. This IC can act as a failsafe device, protecting the system from accidental triggers or attacks.

The TPS3123G15DBVT provides a wide operating range with a low gate drive output and a robust architecture, which ensure reliable operation over a wide variety of loads. This low-power supervisor can also be used in multiple pieces of equipment as it is both low-voltage tolerant and tolerant to overshoot on input and discharge. Its features make it suitable for a variety of system reset applications including power up sequencing and sequencing in fast applications.

The TPS3123G15DBVT has an integrated brown-out detector (BOD) that monitors the power supply voltage level to detect a transient power dip. The brown-out detector then issues a reset signal to the system when the BOD voltage drops below a predetermined voltage (V BOD ). The reset signal will be maintained until the power supply voltage recovers to the preset level.

The TPS3123G15DBVT is also equipped with an internal power-on reset (POR) circuit that monitors the power-on voltage. When the power-on voltage rises above a specific threshold value (V POR ), the reset is issued and maintained until the power is removed.

In addition the TPS3123G15DBVT has an active-high reset output (RESET) that is driven by the integrated Comparator. This comparator monitors the voltage at the reset input (RESIN) and issues a reset (RESET) signal as soon as the voltage drops to a preset voltage (V LOW ). This reset signal remains active until the voltage at the reset input (RESIN) rises above the preset voltage (V HIGH ).

The TPS3123G15DBVT also provides a watchdog timer. The watchdog is a circuit that is used to detect if the system is functioning properly or not. The watchdog monitors a signal, usually connected to an I/O pin, and if the signal does not change as expected, then the watchdog will issue a reset signal. This reset signal is issued until the signal is again as expected.

In summary, the TPS3123G15DBVT is a low power supervisor IC that is used to reset a system on power spikes or as a result of a cascading reset. This supervisor provides a wide range of features that make it suitable for use in a variety of system reset applications including power up sequencing and sequencing in fast applications. This IC has an integrated brown-out detector, power-on reset circuit, an active-high reset output, and also provides a watchdog timer. As a result, the TPS3123G15DBVT is a great solution for low-power system reset applications.
