The BD3573YHFP-MTR is a three-phase synchronous rectification voltage regulator from Rohm, belonging to the PMIC - Voltage Regulators - Linear category. It is designed for use in automotive electronic applications such as engine control units (ECUs), engine heaters, and anti-lock brake systems (ABS) and other vehicle control systems. The product integrates three independent voltage regulator channels, which can be used to deliver an output voltage range of 3.2 V to 12 V at currents ranging from 5 A to 30 A.

The product’s main function is to regulate the output voltage while providing high accuracy and excellent thermal stability, enabling high-frequency switching noise to be filtered and ripple minimized. This enables the power supply circuit to supply stable voltage while raising product efficiency and extending the life of the circuits.

The BD3573YHFP-MTR integrates three low noise high-speed low-dropout linear regulators such as shift control step-down, hysteresis control step-down, and hysteresis control step-up. These regulators have built-in feedback (FB) and sync (SY) pins which can be connected when necessary.

The shift control step-down regulator is capable of delivering an output current of up to 30 A. It can control the output voltage by connecting an external resistor to its FB pin and a sync signal to its SY pin. It has an adjustable reference voltage of 1.25 V that can be set through an external resistor.

The hysteresis control step-down regulator is designed to reduce power consumption and improve efficiency while delivering a maximum of 3.0 A output current. It is designed to maintain accurate output voltage regulation even in situations where the input power supply is unstable. An external resistor is connected to the FB pin and a sync signal to the SY pin in order to control the output voltage.

The hysteresis control step-up regulator is designed to provide an output voltage up to 12 V using an external resistor to control the output voltage. It has a maximum output current of 3.0 A and is designed to maintain precise output voltage regulation even in situations where the input power supply is unstable.

The BD3573YHFP-MTR includes a variety of integrated features, including over-voltage protection, over-current detection, shutoff delay time control, thermal shutoff, and an output current monitor. The product is small in size and easy to use with its built-in short circuit protection, making it convenient and reliable for automotive electronic applications.

In conclusion, the BD3573YHFP-MTR is a high-efficiency three-phase synchronous rectification voltage regulator that can be used in a variety of automotive electronic applications. With its integrated features, compact size, and excellent thermal stability, it is a reliable, efficient, and cost-effective solution for a number of automotive applications.
