PMIC - Supervisors

The ADM6348-33ARTZ-R7 Integrated circuit (IC) is a low-power supervisor solution mainly used in system powered by 3V battery. The devices come with one low-voltage reset (LVR) output and one supply voltage supervisor (SVS) output, which are triggered when the LVR or SVS input reaches the threshold which can be programmed by the user.

Application Fields

ADM6348-33ARTZ-R7 can be widely used in soft-start circuits and system activation trigger to help reduce the inrush current and improve the system startup performance. It can also be used in a power down reset trigger unit, as well as in system reliability monitoring, voltage and signal recovery. In addition, the device can be used with other peripheral products such as accelerometers and signal transmitters, so that it can activate or reset the system during the signal disturbance, and then resume the normal operation in time.

Working Principle

ADM6348-33ARTZ-R7 is an ideal choice for many applications because of its low-power requirements and multi-function capabilities. The LVR and SVS outputs will be triggered at the same time when the input voltage rises to the LVR voltage setting or falls below the SVS voltage setting. As shown in the schematic below, when the input voltage falls below the SVS threshold, the SVS output (pin 3) will become active and the LVR output (pin 2) will remain low. On the other hand, when the input voltage rises above the LVR voltage setting, the LVR output will become active and the SVS output will remain low.

The ADM6348-33ARTZ-R7 is also equipped with a power-on reset (POR) feature to provide the system power-on reset when the voltage rises above the POR threshold (which is internally set to 3. 4V). When the POR is triggered, the reset signal will be released and the LVR output will become active.

In addition, the ADM6348-33ARTZ-R7 is equipped with an adjustable delay time feature to delay the LVR output signal release time. This feature can be adjusted by connecting a delay capacitor to the DELAY pin of the device. When the capacitor is ready, the delay time of the LVR output signal will be determined by the delay capacitor connected to the device, and the delay time can be precisely calibrated.

Finally, the ADM6348-33ARTZ-R7 is a high-speed switching device and its typical switching speed is 350ns, which is suitable for most applications. Moreover, the device ensures low quiescent current, making it an ideal choice for batteries or other power saving solutions.

Conclusion

In conclusion, ADM6348-33ARTZ-R7is an excellent power-on reset and voltage supervisor device, perfectly suited for applications requiring low power and fast response time. With its low-power requirements, adjustable delay time, and multi-function capabilities, ADM6348-33ARTZ-R7 is an ideal choice for system reliability monitoring, voltage and signal recovery, and other peripherals.
