PMIC - Supervisors are integrated circuits that provide a variety of voltage and current supervision functions, such as monitoring input supply voltages, resetting controllers, detecting over-current and over-temperature faults, and generating a reset signal.The NCP301LSN42T1G is an example of a PMIC - Supervisors integrated circuit. The NCP301LSN42T1G is a Voltage Supervisor with built-in Latch-off Protection.

The NCP301LSN42T1G provides the essential functions of providing, sequencing, and supervising power supplies in order to protect the system from separate power supply fault conditions, such as Over Voltage Protection (OVP) and Under Voltage Protection (UVP). It is used in a variety of applications including mobile applications, servers, personal computers, embedded controllers, and system monitoring applications.

The main application field of the device NCP301LSN42T1G is for monitoring the microprocessor supply voltage. It can provide a highly accurate Over Voltage Protection (OVP) and Under Voltage Protection (UVP) threshold and output a reset signal to protect the system from supply faults. The NCP301LSN42T1G is also used in power-on sequencing and reset functions where it is capable of generating a reset pulse, with a programmable delay, once the MCP power supply has crossed a threshold. The reset voltage and duration can also be programmed for in-system reset applications.

The NCP301LSN42T1G provides a voltage supervisor which can be configured to monitor input voltages and detect any over-voltage or under-voltage faults. It has a low supply current of 1 μA and can operate down to 1.8V.The reset output can be configured to provide a manual reset and an automatic reset once the input voltage rises above a programmed threshold.It features programmable reset thresholds, reset duration, hysteresis, and power-on reset delay.

In addition, the NCP301LSN42T1G includes Latch-Off Protection. This feature provides protection against damage from overpowering or over voltage events.It will detect a fault on V DD and latch off the reset output, preventing further operation of the system.The reset output is kept in the latched off state until a power-on reset is performed.

In summary, the NCP301LSN42T1G is an example of a PMIC - Supervisors integrated circuit. It can provide Over Voltage Protection (OVP), Under Voltage Protection (UVP), Power-on Reset and Sequence, Manual Reset, and Latch-Off Protection functions with accuracy and low power consumption. It is used in different applications such as mobile applications, servers, personal computers, embedded controllers, and system monitoring applications where protection against separate power supply fault conditions is desired.
