NCV8401DTRKG is an integrated three-channel power distribution switch, load driver and current regulator targeted for automotive audio applications. It is a highly reliable device with a wide range of operating temperature and low quiescent current. In addition to maintaining a regulated output current, the integrated PWM driver provides a low harmonic distortion (THD) listening experience to the listener.

The NCV8401DTRKG is a Power Management IC (PMIC) that includes three independent channels. Each channel can be independently configured as a power distribution switch or load driver. When configured as a power distribution switch, the NCV8401DTRKG is capable of controlling high current/voltage loads with low on-resistance and fast switching. When configured as a load driver, the NCV8401DTRKG can source up to 2A of current to drive high-temperature, high-power devices such as actuators and motors. The integrated PWM driver contained in the device provides a reduced harmonic distortion listening experience for automotive audio applications.

Application field

The NCV8401DTRKG is designed for use in automotive audio applications. It provides a cost-effective, efficient solution for powering high-power loads while reducing power waste and providing a high level of reliability. The device is optimized to provide low-resistance switching to effectuate fast, robust switching of power rails. Additionally, the integrated PWM driver reduces EMI, preventing unwanted noise from entering the audio system.

The NCV8401DTRKG also is suitable for use in embedded system applications that require tight control of power supply circuits. The device can be programmed to provide optimized power for various components by switching and controlling current. This allows for a more reliable, cost-efficient solution than a more conventional discrete control board.

Working Principle

The NCV8401DTRKG is an integrated power management IC that includes three independent channels. Each channel can be independently configured to act as a power distribution switch or a load driver. When configured as a power distribution switch, the channel’s FET will allow current to pass through when enabled and will block current flow when disabled. The FETs can be quickly turned on and off by asserting an appropriate logic level on the control pin. The FETs have a low on-resistance (RDSon) which allows for fast, efficient switching of power rails.

When configured as a load driver, the NCV8401DTRKG is capable of supplying up to 2A of current. The load driver operates by converting a logic signal into an analog voltage source which is used to control the current. In this configuration, the device acts as a precision current source, as the current is adjusted with each PWM cycle. Additionally, the integrated PWM driver adds a signal conditioning layer to reduce electromagnetic interference.

The integrated PWM driver in the NCV8401DTRKG utilizes a Pulse Width Modulation (PWM) algorithm to control the current. The PWM signal has three components: the pulse width, the switching frequency, and the duty cycle. The pulse width represents the duration of each PWM cycle, the switching frequency determines how fast the current is adjusted, and the duty cycle determines how much of the PWM cycle is high (on) and how much is low (off). By varying the PWM signals, the NCV8401DTRKG can accurately deliver a specific amount of current to the load.

The NCV8401DTRKG is an integrated device that offers a cost-effective and efficient approach for managing power supply circuits. The device is suitable for use in automotive audio and embedded system applications, and is capable of providing low-resistance switching, load driving and PWM signal conditioning. The integrated PWM driver reduces harmonic distortion and provides a improved listening experience for automotive audio applications, while the power distribution switch and load driver enable efficient power management.
