The TPS3106E09DBVRG4 is a supervisor integrated circuit that offer Reset and Power-Good output. It keeps the system active, safe, and running smoothly in a wide range of industrial, consumer, and communication applications. This PMIC not only protects circuits against over-voltage, inrush, and under-voltage but also offers precise under-voltage window and supply tracking. It is available in a small 28-pad package.

The TPS3106E09DBVRG4 offers Adaptive Multi-Rate (AMR) reset where the reset output is triggered when the monitored supply voltage drops below the trip level for longer than the previously established reset timer delay. This trip level and reset timer delay can be programmed with a simple resistor divider network. The Power-Good output is an open drain whose output is active low. It switches off when the reset output is active.

The TPS3106E09DBVRG4 is designed with an internal voltage detection circuit and a comparator circuit. The internal voltage detection circuit is formed by accurately matched resistors, and can be monitored for voltage levels at either the VIN pin or the VOUT pin. The output of the voltage detection circuit is sent to the comparator circuit, which compares the voltage levels at VIN and VOUT pins with the trip level voltage. When the voltage levels fall below the set trip level, the comparator output changes its logic level. This causes the reset output pin to be pulled low and trips the power good output pin off. If the VOUT voltage continues to drop somewhere between its minimum operating voltage and the trip level, the on/off ratio of the Power Good output more than doubles to ensure no false reset signals.

The TPS3106E09DBVRG4 offer high accurate under-voltage reset detection, a power-suppy tracking feature, and provide a dual reset to ensure reliable system reset. It is a perfect solution for battery-powered applications such as portable handheld equipment and mobile phones. This PMIC also works great in automotive, communication, and industrial applications. The TPS3106E09DBVRG4 is a low cost, low power, and efficient supervising solution.
