Renesas Electronics 

ISL8013A

Electrical Specifications Unless otherwise noted, all parameter limits are established over the recommended operating conditions and

the typical specification are measured at the following conditions unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are

at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to +85°C. (Continued)
