PMIC (Power Management IC) is a type of integrated circuit (IC) that provides efficient power flow management solutions for computers and other electronic devices. They provide direct control of power supplies, as well as fault protection, which minimizes power losses in operation. Supervisors are a subset of PMICs used to control the operation of microprocessor or microcontroller systems. LM3705XBMM-463/NOPB is a supervisor IC that offers reliable power management for systems in a wide range of consumer and industrial applications.
LM3705XBMM-463/NOPB is an integrated overvoltage, undervoltage, and overcurrent protection supervisor designed for use in hot-plug, high power applications. The device monitors an input voltage and provides an output signal whenever the input voltage falls below an acceptable level or exceeds an overvoltage level. It can also detect and protect against short circuits, current spikes, and other activities that can cause excessive current flow. In addition, the device has an integrated watchdog timer to detect and warn of any power supply interruptions that may occur.
The LM3705XBMM-463/NOPB includes two independent power rails. The first is an LVT (low voltage) rail, which controls the low-voltage level voltage sources, such as processors, memory, and other logic components. The second is a HVT (high voltage) rail, which controls the high-voltage level components, such as DC-DC converters and gate drivers.
The LVT rail of the device is protected against overvoltage events by an adjustable overvoltage comparator. The output of the device is pulled low in overvoltage situations, indicating a fault and to flag a system reset. This can be connected to a microcontroller or processor that can then decide if to initiate a shutdown of the system.
The HVT rail can be protected against short-circuits and overloads, by an adjustable current limit comparator. When the limit is exceeded, the output of the device is pulled to a logical low value, again indicating a fault and to reset the system. The HVT rail is also protected against overvoltage and undervoltage events by the adjustable overvoltage and undervoltage comparators.
The response time of the device is adjustable and ranges from 7-150 microseconds. This can be used to set the threshold voltage levels and to adjust the time taken by the system to enter a reset state in case of an overvoltage or undervoltage event, providing maximum protection for the system.
The LM3705XBMM-463/NOPB also includes Thermal Shutdown circuitry to protect the device in extreme temperature situations. This will shut off the output of the device when the temperature of the device reaches a certain limit, thus preventing any further damage to the system due to overheating. The device also includes an auto-restart feature that allows the device to reset itself after the temperature has returned to an acceptable level.
In conclusion, the LM3705XBMM-463/NOPB supervisor IC provides an excellent solution for systems requiring voltage and current protection against a wide variety of events. The device includes two separate power rails, along with adjustable overvoltage, undervoltage, and current limit protection. In addition, the response time is adjustable, and the device includes a Thermal Shutdown and Auto-Restart feature for further protection of the system. These features make the LM3705XBMM-463/NOPB a great choice for any system requiring reliable power management.
