The NCP304LSQ25T1G is a monolithic power management integrated circuit (PMIC) that belongs to the Supervisors product category. It is designed to provide protection to sensitive microprocessors or application-specific integrated circuits (ASICs) from changes in system power and external threats such as short circuits and electrostatic discharge. The device offers a wide range of features and benefits, making it suitable for use in a variety of applications.

The NCP304LSQ25T1G provides input/output (I/O) monitoring, regulator sequencing, overvoltage protection, and power-on reset functions. It also features a Temperature Monitor Output (TMO) pin which allows users to monitor the temperature of the circuit’s components in real time.

The regulator sequencing feature allows users to implement a system start-up sequence that ensures all of the circuit’s components are powered up in the correct order. This helps to prevent damaging overcurrent conditions caused when a high current device is powered on before other components in the system.

The device’s integrated overvoltage protection helps to prevent damage caused by voltage spikes. This feature monitors the voltage of the circuit and turns off the system power when the voltage rises above a programmable threshold. This helps to protect sensitive components from damage caused by excessively high voltages.

The NCP304LSQ25T1G also provides a power-on reset (POR) feature. This feature monitors the system voltage and will reset the system to its defined power-on state whenever the voltage drops below a programmable level. This provides a fail-safe feature for the system and prevents the unit from becoming stuck in an unknown state.

The NCP304LSQ25T1G is designed for use in a variety of applications, including battery operated products such as smartphones and laptops, as well as telecommunications equipment and industrial electronics. It is also suitable for use in applications that require a temperature monitoring and re-adjustment of the system power at high temperatures.

The NCP304LSQ25T1G operates in the the VAC range of 2.0V to 5.5V and with a supply current of typically only 4µA. The device is offered in a leadless 16-pin Power Package that measures only 2.0mm x 1.5mm, allowing it to fit in even the most space constrained applications. It also features an exceptionally fast 1µs response time, allowing it to detect and respond to changes in the power supply quickly, improving system reliability.

In summary, the NCP304LSQ25T1G is an advanced power management IC that is designed for use in applications that require input/output monitoring, regulator sequencing, overvoltage protection and power-on reset functions. It is offered in an industry standard 16-pin Power Package that allows it to fit in even the most space constrained applications, and its exceptionally fast 1µs response time ensures it can react quickly to changes in system power.
