Logic Compatible Undervoltage Lockout for Both High-Side and Low-Side Outputs Description The IX is a high voltage integrated circuit that can drive high speed MOSFETs and IGBTs that operate at up to +. The IX is configured with independent high-side and low-side referenced output channels, both of which can source and sink A. The floating high-side channel can drive an N-channel power MOSFET or IGBT from the common reference. Manufactured on IXYS Integrated Circuits Division's proprietary high-voltage BCDMOS on SOI (silicon on insulator) process, the IX is extremely robust, and is virtually immune to negative transients. The U circuit prevents turn-on of the MOSFET or IGBT until there is sufficient BS or supply voltage. The IX is available in a -pin SOIC package.

Three input signals (HIN, LIN, and SD) determine the state of the gate driver outputs ( and ). HIN controls via a high voltage interface. The high voltage interface is integrated into the bootstrap supply by using two diodes (DD and DD). A two-stage bootstrap supplies current to the high side and mid level circuitry. The two bootstrap circuits are identical, and careful board layout and positioning of the bootstrap components are required. Resistors RD and RD form a resistive divider to keep the mid supply very near the center of the high voltage supply range. High value resisters (M ) are recommended to minimize power dissipation. The two-stage bootstrap supply reduces the high side gate drive voltage ( B - S ) by two diode forward voltage drops ( F ). Therefore, the supply range for the application circuit shown is: The high side bootstrap capacitor selection is a function of the switching frequency and the on-time (t ONTIME ) of the high side source driver. The quiescent BS current (I QBS ) is supplied by bootstrap capacitor CB, and the quiescent BMSM supply current (I QBMSM ) is supplied by bootstrap capacitor CB. To insure adequate supply current: and: t ONTIME CB I QBS --------------------------------------------------------------------------------------------- BSU+ + F + CE sat M t ONTIME CB I QBMSM --------------------------------------------------------------------------------------------- BSU+ + F + CE sat M BSU+ + F + CE sat M Where CE(sat) M is the saturation voltage of IGBT, M.

IX Manufacturing Information. Moisture Sensitivity All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits Division classified all of its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint industry standard, IPC/JEDEC J-STD-, in force at the time of product evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee proper operation of our devices when handled according to the limitations and information in that standard as well as to any limitations set forth in the information or standards referenced below. Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced product performance, reduction of operable life, and/or reduction of overall reliability. This product carries a Moisture Sensitivity Level (MSL) classification as shown below, and should be handled according to the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-. Device Moisture Sensitivity Level (MSL) Classification IXB MSL. ESD Sensitivity This product is ESD Sensitive, and should be handled according to the industry standard JESD-.. Soldering Profile Provided in the table below is the Classification Temperature (T C ) of this product and the maximum dwell time the body temperature of this device may be above (T C - )ºC. The classification temperature sets the Maximum Body Temperature allowed for this device during lead-free reflow processes. For through hole devices, and any other processes, the guidelines of J-STD- must be observed. Device Classification Temperature (T C ) Dwell Time (t p ) Max Reflow Cycles IXB C seconds. Board Wash IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. Board washing to reduce or remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage to the device. These precautions include, but are not limited to: using a low pressure wash and providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature and duration necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be used. Additionally, the device must not be exposed to flux or solvents that are Chlorine- or Fluorine-based. www.ixysic.com R
