Terminal Position: DUAL

Having dual terminal positions allows for flexibility in PCB layout and design, making it easier to integrate the IC into various circuit configurations.

Maximum Seated Height: 1.2 mm

The low maximum seated height of 1.2 mm enables a compact design and reduces the overall height of the PCB assembly, especially important for space-constrained applications.

Width (mm): 4.4 mm

With a narrow width of 4.4 mm, the IC can fit into tight spaces on the PCB, providing more flexibility in the layout and design of the electronic system.

Other IC type: BRUSHLESS DC MOTOR CONTROLLER

As a brushless DC motor controller, this IC is specifically designed for controlling the operation of brushless DC motors, offering precise and efficient motor control capabilities.

Minimum Supply Voltage (Vsup): 18 V

The minimum supply voltage of 18V ensures compatibility with a wide range of power sources and allows for operation in various voltage conditions.

Length: 9.7 mm

With a compact length of 9.7 mm, the IC takes up minimal space on the PCB, enabling efficient use of board real estate and facilitating compact designs.

Maximum Supply Current (Isup): 8 mA

The low maximum supply current of 8 mA results in low power consumption, making the IC energy-efficient and suitable for battery-powered applications.

Terminal Form: GULL WING

The gull wing terminal form provides mechanical strength and secure connections to the PCB, ensuring reliable electrical performance and ease of assembly.

Terminal Pitch: 0.5 mm

The fine terminal pitch of 0.5 mm allows for high-density mounting on the PCB, enabling a compact layout and reducing signal interference for improved performance.

Maximum Supply Voltage (Vsup): 50 V
