The NCT3016Y TR is an application-specific integrated circuit (ASIC) designed for use in embedded systems as a power monitoring and control solution. The device is part of the National Semiconductor PowerWise™ family, a line-up of specialized power management products designed to maximize power efficiency and reduce system costs.

The main features of the NCT3016Y TR are: a wide voltage output range of 4.5V to 22V, a low quiescent current rating of 40uA and on-chip programmable temperature limit of 150 degrees Celsius for safety. The current limit and operating temperature can be programmed using the on-board resistor and capacitor. The device is lead-free and RoHS compliant for environmental safety.

The primary application of the NCT3016Y TR is in embedded systems that require an integrated power monitoring and control solution. Its low current and voltage range makes it applicable for low power design, as well as for applications that require continuous monitoring and control of current (96 mA to 32 A) and voltage up to 22V. It can be used to protect sensitive systems from under-voltage and over-current conditions, as well as to activate system specified power saving modes. This makes the NCT3016Y TR ideal for embedded system control, communications and industrial equipment.

The working principle of the NCT3016Y TR is based on line regulation and current limit sensing. The output voltage and current is monitored, and is limited to the programmed values. The device is made up of four integrated circuits that are cascaded to provide precision current, voltage and temperature monitoring. A voltage reference, error amplifier and a peak current detector circuitry is included to accurately sense and control the output current and voltage. The device uses a simple configuration involving external resistors to set the current limit, voltage limit and thermal limit. Additionally, the device supports external sleep mode control and current monitoring, enabling quick response and accurate control.

The single supply, low current consumption and integrated protection mechanisms of the NCT3016Y TR make it a low cost power management solution for embedded systems. Its wide operating voltage range, precise current detection and temperature limit options makes it versatile as a power monitoring and control solution, applicable to many system architectures.
