NCV300LSN36T1G

PMIC - Supervisors, referred to as power management integrated circuits (PMIC), are electronic components designed to deliver essential power supply functions. The NCV300LSN36T1G PMIC is an example of a single supervisor that can provide an effective and reliable solution in various applications.

The NCV300LSN36T1G is a 3.6V voltage supervisor, with a maximum monitoring voltage of 2.2V and a guaranteed reset voltage of VDD-0.15V (minimum 0.8V). The reset threshold voltage is adjustable from 1.25V to 2.2V, and the reset output is a 200kHz open drain pulse with a width of 100ms maximum. The PMIC also supports the programmable reset timeout feature, allowing the user to customize reset activation time (default 4ms).

This flexible PMIC features a high tolerance to supply voltage variations and is perfectly suited for battery-powered applications, providing excellent protection against power failures and voltage transients. It also includes an active internal pullup circuit and an active internal pulldown resistor, allowing the user to set the reset signal during power-on as either high or low. The integrated monitor signal also allows for the power supervisor to detect power supply voltage irregularities, and it is made available at its monitoring pin.

The NCV300LSN36T1G has a wide range of applications, i.e., to monitor microprocessor voltages and protect against current surges and levels, to monitor the output voltage of power converters and regulators, and to provide various over-voltage and under-voltage monitoring functions. It can also be used in consumer electronics, automotive and portable applications.

The working principle of the NCV300LSN36T1G is quite simple and straightforward. It consists of a monitor signal that is compared to a preset voltage reference level. When the input voltage exceeds the preset level, a reset signal is generated triggering a reset function. The output enable signal and reset signals are then used to initiate a reset process. In the case of over-voltage protection, the power supervisor monitors to ensure that the voltage does not exceed a certain level and, if it does, an alarm or reset signal is triggered. Similarly, for under-voltage protection, the power supervisor monitors to ensure that the voltage does not drop below a certain level and, if it does, a reset signal is generated.

In summary, the NCV300LSN36T1G PMIC supervisor is a highly integrated and reliable solution for various applications. Its flexibility, usability and adjustable reset threshold voltage, reset pulse width and timeout make it an ideal choice for power supply design and power management. Its wide range of applications and its simple working principle make it a popular choice for providing reliable power management solutions.
