NCP4350DR2G is a chip from the family of PMIC (Power Management Integrated Circuit)-Supervisors. It is a low-noise, dual voltage supervisor designed to monitor 1.8V to 5.5V power supply and provide two independent power-good outputs. This device is suitable for wide range of applications including AdvancedTCA, CompactPCI, SCSI, data storage, and DDR memory modules. It is equipped with 1-bit non-volatile memory, and has internal power-on-reset circuit that can be enabled/ disabled as per user’s requirements.

With its small size of 1.3mm x 1.3mm and one-sensor multiple threshold feature, NCP4350DR2G is the best option for low-power, space-constrained designs which require the flexibility to accurately control the power supply and charge up the capacitors. The NCP4350DR2G can operate from a 2.5V to 4.8V supply voltage, and is offered in a tiny WLCSP package.

The NCP4350DR2G has two sets of independent power good outputs, each with its own threshold voltage range from 1.8V to 5.5V. The device can monitor both voltage domains at the same time, and is capable of generating an active low signal when the corresponding threshold voltage is reached. This feature is especially useful for applications that require voltage monitoring of two different rails at the same time.

In addition to dual power-good outputs, NCP4350DR2G also provides an internal power-on reset (POR) circuit. This POR circuit can be used to monitor the external power supply and generate a reset signal when necessary. The POR circuit can be disabled/enabled through an I2C interface at run time, allowing the user to enable/disable the reset signal as required. The POR circuit also provides a programmable delay to prevent false resets due to power supply transients.

The NCP4350DR2G also features a 1-bit non-volatile memory, which enables the device to store a bit of information that stays valid even after a power cycle or reset. This feature is especially useful in applications requiring storing of settings upon power-down, such as advanced gaming systems or data storage devices.

The NCP4350DR2G is a very useful chip for low-power, space-constrained designs. Its small size, combined with its many features, makes it the ideal choice for a variety of applications. With its dual independent power-good outputs, internal POR circuit, and 1-bit non-volatile memory, the NCP4350DR2G can be used to accurately control the power supply and charge up the capacitors in a wide range of applications including AdvancedTCA, CompactPCI, SCSI, data storage, and DDR memory modules.
