Characteristics deterioration of the IC or damage may result if an instantaneous voltage surge exceeding the maximum rated value is applied to the VM line due to coil kickback or other causes. *2 : The output constant current (IOUT) is determined by the internal reference voltage and the sense resistor between the ISET and SGND pins. IOUT = Internal reference voltage (0.2V) ÷ Sense resistor (RSET) From the formula above, IOUT = 5mA when a sense resistor of 40Ω is connected between the ISET and SGND.
