PRODUCTION DATA
IOUT_LIMIT is shown in Figure 7-17 and described in Table 7-5.
Return to Summary Table.
IOUT_LIMIT sets the current limit target voltage between the ISP pin and the ISN pin. The default value in the current limit register is 11100100b standing for 50 mV. 1 LSB stands for 0.5 mV. The bit7 enables the current limit or disables the current limit.
