Note 1.

Exceeding the absolute maximum rating may damage the device.

Note 2.

The device is not guaranteed to function outside its operating rating.

Note 3.

Devices are ESD sensitive. Handling precautions recommended.

Note 4.

Specification for packaged product only.

Note 5.V

CC5 IN is not required for operation.

Note 6.

CC3 IN powers all internal logic, bias, and drive circuitry, and is required for operation.

Note 7.

L = 1kΩ connected to ground.

Note 8.

Measurement is from the Hi-Z- or 0V-state command to the beginning of the slope. Measurement does not apply when device is in current

limit or thermal shutdown.

Note 9.

L = 10Ω connected to ground.
