2EDN752x / 2EDN852x
Fast, precise, strong and compatible
• Highly efficient SMPS enabled by 5 ns fast slew rates and 17 ns propagation delay precision for fast MOSFET
and GaN switching
• 1 ns channel-to-channel propagation delay accuracy enables safe use of two channels in parallel
• Two independent 5 A channels enable numerous deployment options
• Industry standard packages and pinout ease system-design upgrades
The new Reference in Ruggedness
• 4.2 V and 8 V UVLO (Under Voltage Lock Out) options ensure instant MOSFET protection under abnormal
conditions
• -10 V control and enable input robustness delivers crucial safety margin when driving pulse-transformers or
driving MOSFETs in through hole packaging
• 5 A reverse current robustness eliminates the need for output protection circuitry.
Typical Applications
• Server SMPS
• TeleCom SMPS
• DC-to-DC Converter
• Bricks
• Power Tools
• Industrial SMPS
• Motor Control
• Solar SMPS
Example Topologies
• Single and interleaved PFC
• LLC, ZVS with pulse transformer
• Synchronous Rectification
Description
The 2EDN752x/2EDN852x is an advanced dual-channel driver. It is suited to drive logic and normal level MOSFETs
and supports OptiMOSTM, CoolMOSTM, Standard Level MOSFETs, Superjunction MOSFETs, as well as IGBTs and
GaN Power devices.
The control and enable inputs are LV-TTL compatible (CMOS 3.3 V) with an input voltage range from -5 V to +20 V.
-10 V input pin robustness protects the driver against latch-up or electrical overstress which can be induced by
parasitic ground inductances. This greatly enhances system stability.

Functional Description
Gate Drive Outputs held active low in case of floating inputs ENx, INx or during startup or power down once UVLO
is not exceeded. Under any situation, startup, UVLO or shutdown, outputs are held under defined conditions.
4.5 Undervoltage Lockout (UVLO)
The Undervoltage Lockout function ensures that the output can be switched to its high level only if the supply
voltage exceeds the UVLO threshold voltage. Thus it can be guaranteed, that the switch transistor is not switched
on if the driving voltage is too low to completely switch it on, thereby avoiding excessive power dissipation.
The UVLO level is set to a typical value of 4.2 V / 8 V (with hysteresis). UVLO of 4.2 V is normally used for logic level
based MOSFETs. For higher level, like standard and high voltage superjunction MOSFETS, an UVLO voltage of
typical 8 V is available.
