　　The 2EDL family contains devices, which control power devices like MOS-transistors or IGBTs with a maximum blocking voltage of +600V in half bridge configurations. Based on the used SOI-technology there is an excellent ruggedness on transient voltages. No parasitic thyristor structures are present in the device. Hence, no parasitic latch up may occur at all temperature and voltage conditions.

　　The two independent drivers outputs are controlled at the low-side using two different CMOS resp. LSTTL compatible signals, down up to 3.3V logic. The device includes an under-voltage detection unit with hysteresis characteristic which are optimised either for IGBT or MOSFET.

　　Those parts, which are designed for IGBT have asymmetric undervoltage lockout levels, which support strongly the integrated ultrafast bootstrap diode. Additionally, the offline gate clamping function provides an inherent protection of the transistors for parasitic turn-on by floating gate conditions, when the IC is not supplied via VCC.

　　2EDL系列主要特性:

　　 Thin-film-SOI-technology

　　 Maximum blocking voltage +600V

　　 Individual control circuits for both outputs

　　 Filtered detection of under voltage supply

　　 All inputs clamped by diodes

　　 Off line gate clamping function

　　 Asymmetric undervoltage lockout thresholds for high side and low side

　　 Qualified according to JEDEC1 (high temperature stress tests for 1000h) for target applications

　　2EDL系列产品产品亮点:

　　 Insensitivity of the bridge output to negative transient voltages up to -50V given by SOI-technology

　　栅极驱动评估板EVAL-2EDL23N06PJ

　　The gate driver evaluation board EVAL-2EDL23N06PJ was developed to show the functionalities and key features of the Infineon COOLMOS™ gate driver 2EDL23N06PJ in resonant zero voltage turn-on half-bridge applications. The board EVAL-2EDL23N06PJ is therefore not recommended by default for hard switched operation which leads to hard body diode commutation and hence excessive diode as well as COOLMOS™ losses. Such operation may result to damage of power switches and possibly other circuit components!

　　The board is available from Infineon in sampling quantities. The properties of this part are described in the datasheet chapter of this document, whereas the remaining paragraphs provide information intended to enable the customer to copy, modify and qualify the design for production, according to their own specific requirements.

　　The design of the EVAL-2EDL23N06PJ was performed with respect to the environmental conditions described in this document. The design was tested as described in this document, but not qualified regarding manufacturing, lifetime or over the full ambient operating conditions.

　　The boards provided by Infineon are subjected to functional testing only.

　　Due to their purpose Evaluation Boards are not subjected to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products. These Evaluation Boards are used for development support only and should not be used as reference design for volume production.
