Si8285/86 Data Sheet
ISODrivers with System Safety Features
KEY FEATURES
The Si828x (Si8285 and Si8286) are isolated, high current gate drivers with integrated
system safety and feedback function. The devices are ideal for driving power MOSFETs
and IGBTs used in a wide variety of inverter and motor control applications. The Si8285
and Si8286 isolated gate drivers utilize Silicon Labs' proprietary silicon isolation technol-
ogy, supporting up to 5.0 kVrms withstand voltage per UL1577. This technology enables
higher-performance, reduced variation with temperature and age, tighter part-to-part
matching, and superior common-mode rejection compared to other isolated gate driver
technologies.
The input to the device is a complementary digital input that can be utilized in several
configurations. The input side of the isolation also has several control and feedback digi-
tal signals. The controller to the device receives information about the driver side power
state (Si8285) and fault state of the device and recovers the device from fault through an
active-low reset pin.
On the output side, the Si8285 provides separate pull-up and pull-down pins for the gate.
The Si8286 has a single pin for both functions. A dedicated DSAT pin detects the desa-
turation condition and immediately shuts down the driver in a controlled manner. The
Si8285 device also integrates a Miller clamp to facilitate a strong turn-off of the power
switch.
Automotive Grade is available for certain part numbers. These products are built using
automotive-specific flows at all steps in the manufacturing process to ensure the robust-
ness and low defectivity required for automotive applications.

Why does the output voltage of TPS5430 increase as the input voltage increases?
This is the circuit. If the input is below 12V, the output is 3.3V. If the input is 13V, the power supply output is 3.7V. It should be constant....
