Notes:
1. Derate linearly above 70°C free air temperature at a rate of 0.3 mA/°C.
2. In order to achieve the absolute maximum power dissipation specified, pins 4, 9, and 10 require ground plane connections and may require
airflow. See the Thermal Model section in the application notes at the end of this data sheet for details on how to estimate junction temperature
and power dissipation. In most cases the absolute maximum output IC junction temperature is the limiting factor. The actual power dissipation
achievable will depend on the application environment (PCB Layout, air flow, part placement, etc.). See the Recommended PCB Layout section
in the application notes for layout considerations. Output IC power dissipation is derated linearly at 10 mW/°C above 90°C. Input IC power
dissipation does not require derating.
3. Maximum pulse width = 10 μs. This value is intended to allow for component tolerances for designs with IO peak minimum = 2.0 A. Derate
linearly from 3.0 A at +25°C to 2.5 A at +105°C. This compensates for increased IOPEAK due to changes in VOL over temperature.
4. This supply is optional. Required only when negative gate drive is implemented.
5. Maximum pulse width = 50 μs.
6. See the Slow IGBT Gate Discharge During Fault Condition section in the applications notes at the end of this data sheet for further details.
7. 15 V is the recommended minimum operating positive supply voltage (VCC2 - VE) to ensure adequate margin in excess of the maximum VUVLO+
threshold of 12.5V. For High Level Output Voltage testing, VOH is measured with a dc load current. When driving capacitive loads, VOH will
approach VCC as IOH approaches zero units.
8. Maximum pulse width = 1.0 ms.
9. Once VO of the ACPL-333J is allowed to go high (VCC2 - VE > VUVLO+), the DESAT detection feature of the ACPL-333J will be the primary source of
IGBT protection. UVLO is needed to ensure DESAT is functional. Once VCC2 is increased from 0V to above VUVLO+, DESAT will remain functional
until VCC2 is decreased below VUVLO-. Thus, the DESAT detection and UVLO features of the ACPL-333J work in conjunction to ensure constant
IGBT protection.
10. See the DESAT fault detection blanking time section in the applications notes at the end of this data sheet for further details.
11. This is the “increasing” (i.e. turn-on or “positive going” direction) of VCC2 - VE
12. This is the “decreasing” (i.e. turn-off or “negative going” direction) of VCC2 - VE
13. This load condition approximates the gate load of a 1200 V/150A IGBT.
14. Pulse Width Distortion (PWD) is defined as |tPHL - tPLH| for any given unit.
15. As measured from IF to VO.
16. The difference between tPHL and tPLH between any two ACPL-333J parts under the same test conditions.
17. As measured from ANODE, CATHODE of LED to VOUT
18. This is the amount of time from when the DESAT threshold is exceeded, until the FAULT output goes low.
19. This is the amount of time the DESAT threshold must be exceeded before VOUT begins to go low, and the FAULT output to go low. This is supply
voltage dependent.
20. Fault Reset: This is the amount of time when VOUT will be asserted low after DESAT threshold is exceeded. See the Description of Operation
(Fault Reset) topic in the application information section.
21. Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse, VCM, to assure that the
output will remain in the high state (i.e., VO > 15 V or FAULT > 2 V).
22. Common mode transient immunity in the low state is the maximum tolerable dVCM/dt of the common mode pulse, VCM, to assure that the
output will remain in a low state (i.e., VO < 1.0 V or FAULT < 0.8 V).
23. To clamp the output voltage at VCC - 3 VBE, a pull-down resistor between the output and VEE is recommended to sink a static current of 650 μA
while the output is high. See the Output Pull-Down Resistor section in the application notes at the end of this data sheet if an output pull-down
resistor is not used.
24. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 6000 Vrms for 1 second. This test is
performed before the 100% production test for partial discharge (method b) shown in IEC/EN/DIN EN 60747-5-5 Insulation Characteristic Table.\
25. This is a two-terminal measurement: pins 1-8 are shorted together and pins 9-16 are shorted together.
26. Split resistors network with a ratio of 1:1 is needed at input LED1. See Figure 34.
