3 / 48 page Si88x4x Preliminary Rev. 0.6 3 1. Electrical Specifications Table 1. Recommended Operating Conditions Parameter Symbol Min Typ Max Unit Ambient Operating Temperature* TA –4025125 °C Power Input Voltage VDDP 3.0 — 5.5 V Supply Voltage VDDA 3.0 — 5.5 V VDDB 3.0 — 5.5 V *Note: The maximum ambient temperature is dependent on data frequency, output loading, number of operating channels, and supply voltage. Table 2. Electrical Characteristics1 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 DC/DC Converter Switching Frequency Si8824x, Si8844x FSW 250 kHz Switching Frequency Si8834x, Si8864x FSW RFSW = 23.3 k FSW = 1025.5/(RFSW x CSS) CSS = 220 nF (see Figure 9) (1% tolerance on BOM) 180 200 220 kHz RFSW = 9.3 k FSW = 1025.5/(RFSW x CSS) CSS = 220 nF (see Figure 9) (1% tolerance on BOM) 450 500 550 kHz RFSW = 5.18 k , CSS = 220 nF (see Figure 9) 810 900 990 kHz VSNS voltage VSNS ILOAD = 0 A 1.002 1.05 1.097 V VSNS current offset Ioffset –500 — 500 nA 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. |
