Electrical Characteristics1 (Continued) VIN =24 V; VDDA = 4.3 V (see Figure 3) for all Si8844x/64x; VDDA =VDDP = 3.0 to 5.5 V (see Figure 2) for all Si8824x/34x; TA = –40 to 125 °C unless otherwise noted Parameter Symbol Test Condition Min Typ Max Unit Notes: 1. Over recommended operating conditions as noted in Table 1. 2. VOUT = VSNS x (1 + R1/R2) + R1 x Ioffset 3. VDDP current needed for dc-dc circuits. 4. VDDA current needed for dc-dc circuits. 5. The nominal output impedance of an isolator driver channel is approximately 50 , ±40%, which is a combination of the value of the on-chip series termination resistor and channel resistance of the output driver FET. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces. 6. tPSK(P-P) is the magnitude of the difference in propagation delay times measured between different units operating at the same supply voltages, load, and ambient temperature. 7. Start-up time is the time period from when the UVLO threshold is exceeded to valid data at the output. |
