The BD61245EFV-E2 is an advanced power management integrated circuit (PMIC) designed to drive brushless dc (BLDC) motors. It can output up to 600mA of peak current over a wide range of motor winding voltages, from 0.8V to 6V. It is a highly efficient and cost-effective solution for controlling and driving motors in a wide range of applications, from electric lawnmowers to industrial automation systems.

The BD61245EFV-E2 has a number of features that make it an ideal choice for applications such as mini electric vehicles, robotic actuators, and medical equipment, among others. Its low-voltage start function, for instance, enables the motor to be started from as low as 0.8V, allowing it to be used in energy-starved conditions without risking electric shock or permanent damage.

The integrated ESD protection ensures that the IC is protected from electrical charge shocks, further improving the reliability of the BD61245EFV-E2. It also features an adjustable over-current protection, adjustable start speed and adjustable low-voltage protection to prevent being damaged caused by external conditions. Additionally, the IC incorporates a low-power sleep-mode that reduces power consumption during periods of inactivity.

As far as its working principle is concerned, the BD61245EFV-E2 provides a three-phase motor drive by controlling six outputs, driven by internal regulated logic power supply and pulse width modulation. The logic input voltage is 5V or 3.3V, and the output voltage is equal to that of the motor winding. This means no external power supply is required for the application.

The BD61245EFV-E2 can also be used for two-phase or single-phase applications by configuring the six outputs in different ways. In two-phase applications, two sets of three outputs are configured to drive a two-phase motor. For single-phase application, the four sets of outputs are configured to drive a single-phase motor.

The BD61245EFV-E2 provides protection to its outputs via a set of over-current protection, over-voltage protection, and under-voltage protection. These protections help to ensure the longevity of the motor and the IC itself, while also helping to reduce the risk of malfunction. Additionally, it can detect motor speed and output open-motor, over-temperature and over-load protection, further improving its safety, reliability and usability.

The BD61245EFV-E2 can be used in a wide range of motor driver and controller applications, from medical actuators to electric motors, robotics, and industrial automation systems. It is suitable for a range of motor voltages and provides high efficiency and robust over-current and over-temperature protection. Its low-power sleep mode and adjustable motor speed guarantees that it is an energy-efficient solution and its low-voltage start and adjustable over-current protection extends the lifespan of the motor.
