The MAX9952DCCB+ Integrated Circuit (IC) is an Analog, High-Voltage High-Temperature, High-Speed, Single-Channel Double-Buffered Current Sink designed to drive a single resistor-based current source. It offers efficient and cost-effective solutions for motor control applications, especially in battery-powered applications where the current starved motor supplies a steady current while the battery is depleted. This IC is ideal for applications where low current and low voltage are paramount, such as solar-powered systems and remote monitoring systems. Additionally, the MAX9952DCCB+ can work with a variety of power sources, including both AC and DC power, which increases its flexibility for a wide range of applications.

The MAX9952DCCB+ contains 14 pins of active electronics and a 9-pin header for connecting the external current-sense resistor. This includes a low-dropout regulator (LDO) that allows for efficient current management. Additionally, the IC has a wide range of operating temperature window and it is rated for use in applications up to 160°C. It also works with a very low quiescent current of only 7 μA.

The MAX9952DCCB+ is a high-speed IC with a switching frequency of 2MHz and a drain voltage of up to 380V. It has five logic power pins, seven control pins, and two analog inputs. This IC also has two digital outputs which can be used to control circuit parameters such as gain and slew rate, so that the current supplied by the IC can be precisely controlled. The MAX9952DCCB+ also offers additional features such as thermal protection, an adjustable fault-current level, and a separate power supply for the IC.

The working principle of the MAX9952DCCB+ is straightforward. It operates by providing a sink current that is regulated by an external precision resistor. This resistor is used to sense the current passing through the circuit, and then it is applied to the voltage reference input, resulting in a regulated DC output. This output current is then buffered to provide a very fast response time to ensure smooth and precise control. Additionally, the MAX9952DCCB+ has an integrated frequency generator that allows it to automatically adjust its output current according to changes in load conditions. This feature helps reduce heat dissipation, which is ideal for motor control applications.
