Si823Hx Data Sheet
4.0 A Symmetric Drive ISODrivers with Low Propagation Delay
and High Transient Immunity
The Si823Hx combines two isolated gate drivers into a single package for high power
applications. The Si823Hx includes devices with single or dual control inputs with in-
dependent or high-side/low-side outputs. These drivers can operate with a 3.0 – 5.5 V
input VDD and a maximum drive supply voltage of 30 V.
The Si823Hx is ideal for driving power MOSFETs and IGBTs used in a wide variety of
switched power and motor control applications. These drivers utilize Silicon Labs' pro-
prietary silicon isolation technology, supporting up to 5 kV
RMS
for 1 minute isolation
voltage. This technology enables high CMTI (125 kV/µs), lower propagation delays
and skew, little variation with temperature and age, and low part-to-part matching.
The unique architecture of the output stage features a booster device that provides a
higher pull up capability at the Miller plateau region of the load power switch to sup-
port faster turn-on times. This driver family also offers some unique features such as
over-temperature protection, output Undervoltage Lockout (UVLO) fault detection,
dead time programmability and fail-safe drivers with default low in case of loss of input
side power. The Si823Hx
family offers longer service life and dramatically higher relia-
bility compared to opto-coupled gate drivers.
Automotive Grade is available. These products are built using automotive specific
flows at all steps in the manufacturing process to ensure the robustness and low de-
fectivity required for automotive applications.

Industrial and Automotive Grade OPNs
Industrial-grade devices (part numbers having an “-I” in their suffix) are built using well-controlled, high-quality manufacturing flows to
ensure robustness and reliability. Qualifications are compliant with JEDEC, and defect reduction methodologies are used throughout
definition, design, evaluation, qualification, and mass production steps.
Automotive-grade devices (part numbers having an “-A” in their suffix) are built using automotive-specific flows at all steps in the manu-
facturing process to ensure robustness and low defectivity. These devices are supported with AIAG-compliant Production Part Approval
Process (PPAP) documentation, and feature International Material Data System (IMDS) and China Automotive Material Data System
(CAMDS) listing. Qualifications are compliant with AEC-Q100, and a zero-defect methodology is employed throughout definition, de-
sign, evaluation, qualification, and mass production steps.
