PMIC - Supervisors

The NCP300HSN30T1 is a supervisory circuit applied to the field of Power Management Solutions, and is intended to ensure proper sequencing and reset of core voltage and I/O voltages on a multi-voltage system. This Family of Power Management Circuits helps to reduce power consumption, improve power efficiency and extend battery life.

The NCP3000HSN30T1 IC is a 3V voltage supervisor with a high-current output. It is designed for applications where high voltage thresholds with low quiescent current and high reliability are desired. The IC has a typical quiescent current of 250nA and can monitor a voltage range from 2.9-4.2 Volts. It has an active-low reset output and is capable of driving a wide range of loads, from LEDs to high current loads such as processors.

The NCP300HSN30T1 is suitable for mission critical applications requiring accurate and highly reliable resetting and sequencing. The IC offers a wide selection of reset thresholds, while providing low quiescent power consumption, high current output and small package outlines.

Features and Benefits

• Wide variety of reset thresholds
• Low quiescent current
• High-current output
• Small Package outlines
• Accurately Provide the Reset & Sequencing for Both Core and I/O Voltages

The NCP300HSN30T1 circuit provides the reset and sequencing for both core and I/O voltages when the system is in reset mode and when the system starts up. The reset output is active low and works in the following manner

• When the input voltage falls below the VTH1 threshold, the output is driven low.
• If VIN then falls below the VTH2 reset threshold, the output toggles.
• When the input voltage rises above VTH2, the output is set high.

Applications

• Mobile and Desktop Computing
• Wireless, Network and Communications Systems
• Consumer Electronics and Power Management Solutions
• Aerospace and Automotive Industries

The NCP3000HSN30T1 IC is a reliable and robust voltage supervisor, designed to provide the reset and sequencing of both core and I/O voltages in mission critical applications such as those found in mobile and desktop computing, network and communication systems and other power management solutions. It is capable of driving a wide range of loads while consuming very low quiescent current, making it suitable for battery operated applications. With its variety of reset thresholds it can provide accurate and reliable resetting and sequencing.
