www.fairchildsemi.com FAN7382 Half-Bridge Gate Driver (SOURCING/SINKING : 350mA/650mA) Features Description • Floating Cannel Designed For Bootstrap Operation To +600V. • Typically 350mA/650mA Sourcing/Sinking Current Driving Capability For Both Channels • Common-Mode dv/dt Noise Canceling Circuit • Extended Allowable Negative VS Swing To -9V For Signal Propagation @ VCC=VBS=15V • VCC & VBS Supply Range From 10V To 20V • UVLO Functions For Both Channels • TTL Compatible Input Logic Threshold Levels • Matched Propagation Delay Below 50nsec • Output In-phase With Input The FAN7382 is a monolithic half-bridge gate driver IC for driving MOSFETs and IGBTs, which operate up to +600V. Fairchild’s high voltage process and common-mode noise canceling technique give stable operation of high-side driver under high dv/dt noise circumstances. Advanced level shift circuit allows high-side gate driver operation up to VS=-9.8 V(typ.) for VBS=15V. The input logic level is compatible with standard TTL series logic gates. UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for the applications such as fluorescent lamp ballast, PDP scan driver, motor control, etc. Typical Applications • PDP Scan Driver • Fluorescent Lamp Ballast 1 8SOIC Internal Block Diagram HIGH-SIDE DRIVER UVLO NOISE CANCELLER HIN 2 DELAY R R Q DRIVER LEVEL SHIFTER 8 VB 7 HO 6 VS 1 VCC 5 LO 4 COM S PULSE GENERATION 500kΩ LOW-SIDE DRIVER UVLO 3 DELAY 500kΩ DELAY DRIVER LIN Rev. 0.0.3 ©2005 Fairchild Semiconductor Corporation FAN7382 Pin Assignments HIN 2 LIN 3 FA N 7382 VCC 1 COM 4 8 VB 7 HO 6 VS 5 LO Pin Descriptions 2 Pin No Symbol 1 VCC I/O Decription 2 HIN Logic Input for High Side Gate Driver Output 3 LIN Logic Input for Low Side Gate Driver Output 4 COM 5 LO Low Side Driver Output 6 VS High Voltage Floating Supply Return 7 HO High Side Driver Output 8 VB High Side Floating Supply Low Side Supply Voltage Logic Ground and Low Side Driver Return FAN7382 Absolute Maximum Ratings Parameter Symbol Min.
