9 / 34 page Ver1.0 8 LD1072 16-CH LED DRIVER WITH DOT CORRECTION AND 12-BIT PWM CONTROL ELECTRICAL CHARACTERISTICS (VDD=3V to 5.5V, TA = -40oC to 85) (unless otherwise noted) PARAMETER SYMBOL TEST CONDITION MIN. TYP. MA X. UNI T Thermal error flag threshold T (TEF) Junction temperature *(5) 150 170 ℃ LED open detection threshold V (LED) - 0.3 0.4 V (1) The deviation of each output from the average of OUT0-15 constant current. It is calculated by Equation 1 in Table 1. (2) The deviation of average of OUT1-15 constant current from the ideal constant-current value. It is calculated by Equation 2 in Table 1. The ideal current is calculated by Equation 3 in Table 1. (3) The line regulation is calculated by Equation 4 in Table 1. (4) The load regulation is calculated by Equation 5 in Table 1. (5) Not tested. Specified by design.
