A PMIC - Supervisors, MIC1832M-TR is a voltage supervisor with small-size, low power consumption and high accuracy voltage monitoring capability. The device is ideal for use in systems, such as small handheld devices, where low power consumption and simple power management is required. In addition, the MIC1832M-TR offers built-in protection against over-voltage and under-voltage conditions as well as negative-transition and positive-transition detections.

The MIC1832M-TR operating voltage is between 2.2 V to 5.5 V, while its output enable voltage is between 0.8 V to VDD, and its enable active low/high can be set via external pins. It’s also equipped with a disable bit that can be set to disable or enable the outputs based on a low or high logic level. Additionally, the MIC1832M-TR features a watchdog timer for time-out and reset monitoring. The device also has an internal pull-up that can be enabled/disabled.

The working principle of the MIC1832M-TR is based on the concept of prevention. It utilizes a low-power oscillator to regulate its output voltage. The low-power oscillator works by converting the voltage of the battery into something a digital signal can recognize - a signal whose signal level can be easily detected and compared against a pre-defined threshold value. Whenever the voltage of the battery drops below the threshold, the MIC1832M-TR will activate its output-enabling signal. Similarly, once the voltage of the battery rises back up above the threshold, the MIC1832M-TR will deactivate its output-enabling signal.

The MIC1832M-TR can also be used in combination with other voltage supervisors to monitor and maintain multiple voltage levels with higher accuracy as well as provide protection against power disruptions. Other uses of the device include battery monitoring, power monitoring, system reset, and in-system status indicator. The MIC1832M-TR can be used in systems such as portable devices and industrial automation, as well as in automotive, telecom, and data communication systems.

The MIC1832M-TR is a useful and reliable device for voltage regulation and power management. It is well-suited for systems that require low power consumption as well as protection against over-voltage and under-voltage conditions. Additionally, the device also features an internal pull-up and watchdog timer for time-out and reset monitoring, making it a great choice for a variety of applications.
