Thermal management is a critical component of modern power management architectures. The NE1619DS,112 can help meet the needs of today’s power management applications. The NE1619DS,112 is a power management IC (PMIC) designed specifically to meet the requirements of thermal management applications. It offers high efficiency and reliability, and provides a comprehensive set of features and functions to simplify thermal management design.

The NE1619DS,112 is a dual-channel power supply controller specifically designed for thermal management applications. It is designed to manage up to two fans at two separate supply rails, and it also contains an on-chip EMI filter, as well as a voltage or frequency tracking-mode control. In addition, it offers an optional advanced power saving sleeping mode for when the fan supply is off. It also includes a powerful software-programmable input trigger and output control logic.

The NE1619DS,112 features comprehensive monitoring and protection features that enhance safety, performance, and reliability. It includes over-current, short-circuit, and over-temperature protection features. It also features a versatile voltage detector that can detect voltage levels from 0V to 20V. This voltage detector includes an adjustable timeout for power-supply timing and fault detection.

The NE1619DS,112 has a wide array of operating modes that can be configured to meet the needs of various thermal management applications. It offers three operating modes: manual, automatic, and automatic-ranging. In manual mode, fans are controlled with direct control through external switches. In automatic mode, the fan supply is controlled using temperature-based algorithms programmed via the on-chip configuration registers. Finally, in automatic-ranging mode, the fan supply is controlled using two different temperature ranges.

The NE1619DS,112 provides flexible fan control and also offers a wide range of output current and voltage levels. It offers a selectable output voltage range of 0V to 4.5V, and an output maximum current of 4A. It also has a selectable output current range of 0A to 4.7A. The output switch is equipped with low-side drivers, allowing for easy connection to both open-drain and push-pull configurations.

In addition, the NE1619DS,112 also features a powerful pulse-width modulation (PWM) control circuit. This circuit offers a high-frequency PWM output and an adjustable duty cycle for precise control of the fan speeds. It also allows for fan speed regulation and pacing and offers adjustable hysteresis and debounce times that help reduce power consumption.

The NE1619DS,112 provides a high level of system integration and simplifies designs, leading to a decrease in size, cost, and power consumption. With its comprehensive monitoring and protection features, the NE1619DS,112 is the perfect choice for thermal management applications.
