FAN7393 Half-Bridge Gate Drive IC December 2009 FAN7393 Half-Bridge Gate Drive IC - Floating Channel for Bootstrap Operation to +600V - Typically 2.5A/2.5A Sourcing/Sinking Current Driving Capability - Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VBS=15V - High-Side Output in Phase of IN Input Signal - 3.3V and 5V Input Logic Compatible - Matched Propagation Delay for Both Channels - Built-in Shutdown Function - Built-in UVLO Functions for Both Channels - Built-in Common-Mode dv/dt Noise Cancelling Circuit - Internal 370ns Minimum Dead Time at RDT=0 Ω - Programmable Turn-on Delay Control Dead-Time - High-Speed Power MOSFET and IGBT Gate Driver - Induction Heating - High-Power DC-DC Converter - Synchronous Step-Down Converter - Motor Drive Inverter The FAN7393 is a half-bridge, gate-drive IC with shutdown and programmable dead-time control functions that can drive high-speed MOSFETs and IGBTs operating up to +600V. It has a buffered output stage with all NMOS transistors designed for high-pulse-current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V typical for VBS=15V. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. The high-current and low-output voltage drop feature makes this device suitable for diverse half- and fullbridge inverters motor drive inverters, switching mode power supplies, induction heating, and high-power DCDC converter applications. 14-SOP Ordering Information Package FAN7393M FAN7393MX 14-Lead, Small Outline Integrated Circuit SOIC , Non-JEDEC, Inch Narrow Body, 225SOP Operating Temperature Range -40°C to +125°C Eco Status Packing Method Tube Tape & Reel For Fairchild’s definition of Eco Status, please visit: FAN7393 Half-Bridge Gate Drive IC Typical Application Diagrams +15V PWM IC Control PWM Shutdown RBOOT DBOOT FAN7393 1 IN 2 SD 3 VSS 4 DT 5 COM 6 LO 7 VDD NC 14 VB 13 HO 12 VS 11 NC 10 NC 9 NC 8 Up to 600V R1 CBOOT Load Figure Typical Application Circuit Internal Block Diagram UVLO PULSE GENERATOR 250K SD 2 DT 4 5V 250K SCHMITT TRIGGER INPUT RDTINT SHOOT THOUGH PREVENTION DEAD-TIME DTMIN=370ns HS ON/OFF UVLO LS ON/OFF VSS 3 Pin 8, 9, 10 and 14 are no connection NOISE CANCELLER RR SQ VSS/COM LEVEL SHIFT
