Description
The Si826x isolators are pin-compatible, drop-in upgrades for popular optocoupled gate drivers, such as 0.6 A ACPL-0302/3020, 2.5 A HCPL-3120/ACPL3130, HCNW3120/3130, and similar opto-drivers. The devices are ideal for driving
power MOSFETs and IGBTs used in a wide variety of inverter and motor control
applications. The Si826x isolated gate drivers utilize Silicon Laboratories'
proprietary silicon isolation technology, supporting up to 5.0 kVRMS withstand
voltage per UL1577 and 10kV surge protection per IEC60747. This technology
enables higher-performance, reduced variation with temperature and age, tighter
part-to-part matching, and superior common-mode rejection compared to optocoupled gate drivers. While the input circuit mimics the characteristics of an LED,
less drive current is required, resulting in higher efficiency. Propagation delay time
is independent of input drive current, resulting in consistently short propagation
times, tighter unit-to-unit variation, and greater input circuit design flexibility. As a
result, the Si826x series offers longer service life and dramatically higher reliability
compared to opto-coupled gate drivers.

3. Functional Description
3.1. Theory of Operation
The Si826x is a functional upgrade for popular opto-isolated drivers, such as the Avago HPCL-3120, HPCL-0302,
Toshiba TLP350, and others. The operation of an Si826x channel is analogous to that of an opto coupler, except an
RF carrier is modulated instead of light. This simple architecture provides a robust isolated data path and requires
no special considerations or initialization at start-up. The Si826x also includes a noise filter that suppresses
propagation of any pulse narrower than 15 ns. A simplified block diagram for the Si826x is shown in Figure 9.

4.2. Device Startup
Output VO is held low during power-up until VDD rises above the UVLO+ threshold for a minimum time period of
tSTART. Following this, the output is high when the current flowing from anode to cathode is > IF(ON). Device startup,
normal operation, and shutdown behavior is shown in Figure 10.

4.3. Under Voltage Lockout (UVLO)
The UVLO circuit unconditionally drives VO low when VDD is below the lockout threshold. Referring to Figures 11
through 13, upon power up, the Si826x is maintained in UVLO until VDD rises above VDDUV+. During power down,
the Si826x enters UVLO when VDD falls below the UVLO threshold plus hysteresis (i.e., VDD < VDDUV+ –
VDDHYS).

5. Applications
The following sections detail the input and output circuits necessary for proper operation. Power dissipation and
layout considerations are also discussed.
5.1. Input Circuit Design
Opto driver manufacturers typically recommend the circuits shown in Figures 14 and 15. These circuits are
specifically designed to improve opto-coupler input common-mode rejection and increase noise immunity.

Figure 15. High CMR Si826x Input Circuit
The optically-coupled driver circuit of Figure 14 turns the LED on when the control input is high. However, internal
capacitive coupling from the LED to the power and ground conductors can momentarily force the LED into its off
state when the anode and cathode inputs are subjected to a high common-mode transient. The circuit shown in
Figure 15 addresses this issue by using a value of R1 sufficiently low to overdrive the LED, ensuring it remains on
during an input common-mode transient. Q1 shorts the LED off in the low output state, again increasing commonmode transient immunity.
Some opto driver applications recommend reverse-biasing the LED when the control input is off to prevent coupled
noise from energizing the LED. The Si826x input circuit requires less current and has twice the off-state noise
margin compared to opto couplers. However, high CMR opto coupler designs that overdrive the LED (see
Figure 15) may require increasing the value of R1 to limit input current IF to its maximum rating when using the
Si826x. In addition, there is no benefit in driving the Si826x input diode into reverse bias when in the off state.
Rev. 1.3
17
Si826x
Consequently, opto coupler circuits using this technique should either leave the negative bias circuitry unpopulated
or modify the circuitry (e.g., add a clamp diode or current limiting resistor) to ensure that the anode pin of the
Si826x is no more than –0.3 V with respect to the cathode when reverse-biased.
New designs should consider the input circuit configurations of Figure 16, which are more efficient than those of
Figures 14 and 15. As shown, S1 and S2 represent any suitable switch, such as a BJT or MOSFET, analog
transmission gate, processor I/O, etc. Also, note that the Si826x input can be driven from the I/O port of any MCU
or FPGA capable of sourcing a minimum of 6 mA (see Figure 16C). Additionally, note that the Si826x propagation
delay and output drive do not significantly change for values of IF between IF(MIN) and IF(MAX).

5.2. Output Circuit Design
GND can be biased at, above, or below ground as long as the voltage on VDD with respect to GND is a maximum
of 30 V. VDD decoupling capacitors should be placed as close to the package pins as possible. The optimum
values for these capacitors depend on load current and the distance between the chip and its power source. It is
recommended that 0.1 and 10 µF bypass capacitors be used to reduce high-frequency noise and maximize
performance.
5.3. Layout Considerations
It is most important to minimize ringing in the drive path and noise on the VDD lines. Care must be taken to
minimize parasitic inductance in these paths by locating the Si826x as close as possible to the device it is driving.
In addition, the VDD supply and ground trace paths must be kept short. For this reason, the use of power and
ground planes is highly recommended. A split ground plane system having separate ground and VDD planes for
power devices and small signal components provides the best overall noise performance.

Rev. 1.3
Si826x
5.4. Power Dissipation Considerations
Proper system design must assure that the Si826x operates within safe thermal limits across the entire load range.
The Si826x total power dissipation is the sum of the power dissipated by bias supply current, internal switching
losses, and power delivered to the load, as shown in Equation 1.
P D = I F V F DC + V DD I DDQ + Q d + C L V DD f
where: P D is the total device power dissipation (W)
I F is the diode current (30 mA max)
V F is the diode anode to cathode voltage (2.8 V max)
DC is duty cycle (0.5 typical)
V DD is the driver-side supply voltage (30 V max)
I DDQ is the driver maximum bias current (2.5 mA)
Q d is 3 nC
C L is the load capacitance
f is the switching frequency (Hz)
Equation 1.
The maximum allowable power dissipation for the Si826x is a function of the package thermal resistance, ambient
temperature, and maximum allowable junction temperature, as shown in Equation 2.
T jmax – T A
P Dmax -------------------------- ja
where:
P Dmax is the maximum allowable power dissipation (W)
T jmax is the maximum junction temperature (140 °C)
T A is the ambient temperature (°C)
ja is the package junction-to-air thermal resistance (110 °C/W)
Equation 2.
Substituting values for PDmax Tjmax, TA, and ja into Equation 2 results in a maximum allowable total power
dissipation of 1.0 W. Note that the maximum allowable load is found by substituting this limit and the appropriate
datasheet values from Table 2 on page 4 into Equation 1 and simplifying. Graphs are shown in Figures 17 and 18.
All points along the load lines in these graphs represent the package dissipation-limited value of CL for the
corresponding switching frequency.
