Power semiconductor-based products are widely used in various market applications, including automotive, consumer, communications, industry, medical and aerospace. Among them, power management integrated circuits (PMICs) are devices used to control and convert the electrical energy generated by these semiconductor products into usable and controlled power. PMICs have a wide range of applications and are the backbone devices used in any digital system. The MPC17510AEJ is one of the power management ICs from the automotive segment offered by Mitsubishi. This integrated circuit is a 3-phase brushless DC motor driver for automotive air conditioning (HVAC) applications.

The MPC17510AEJ is a Planar Mosfet 3-phase brushless DC motor driver with a programmable dead-time generato, designed for HVAC applications such as car air conditioning and ventilators. This IC features a wide input voltage range from 8V to 40V, providing high efficiency up to 95%. It also features a programmable PWM frequency range of 0.5kHz to 20kHz and programmable on/off time ratio with a programmable dead-time generator. Additionally, the device has protection mechanisms such as over-voltage, overcurrent and thermal shutdown protection. In terms of power dissipation, the device has a maximum of 6.5W in steady state, while in the dynamic state this drops to 4.5W. This allows the device to have a small footprint and light weight, making it suitable for automotive applications.

The working principle of the MPC17510AEJ is simple and straightforward. When a high voltage is applied to its inputs, the device acts as a motor driver by controlling and regulating the power supply of the motor. The PWM generator circuit generates pulses with duty cycles based on the programmable duty cycle and frequency set by the user. This duty cycle is then fed to the low side gate driver which turns the power MOSFETs on or off in a PWM fashion. This enables the speed of the motor to be regulated and controlled, allowing for precise and accurate motor speeds.

The MPC17510AEJ is ideal for applications such as car air conditioning; ventilators and fan control, e-shutter and lock/unlock systems in vehicles, lamp dimming and intensity control, and speed control of tooling machines. In automotive applications, it has the ability to provide a wide range of safety functions such as thermal shutdown and over-current protection. Additionally, the device can add to the flexibility and robustness of the system by enabling more control and programmability than existing solutions.

In conclusion, the MPC17510AEJ is a 3-phase brushless DC motor driver IC from Mitsubishi, designed for HVAC applications such as car air conditioning and ventilators. It features a wide input voltage range from 8V to 40V, providing high efficiency up to 95%. Additionally, the device has protection mechanisms such as over-voltage, overcurrent and thermal shutdown protection. This allows for precise and accurate motor speeds for various applications. The MPC17510AEJ is thus well suited for applications such as car air conditioning; ventilators and fan control, e-shutter and lock/unlock systems in vehicles, lamp dimming and intensity control, and speed control of tooling machines.
