1 / 12 page ©2005 Fairchild Semiconductor Corporation www.fairchildsemi.com Rev. 1.0.0 Features • Floating Channel Designed For Bootstrapping Operation To +600V • Typically 90mA/180mA Sourcing/Sinking Current Driving Capability For Both Channels • Common-Mode dv/dt Noise Canceling Circuit • Extended Allowable Negative VS Swing To -9.8V 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 • Built-in 100nsec Dead-Time Control Function • Output In-Phase With Input Typical Applications • Fluorescent Lamp Ballast • Compact Fluorescent Lamp Ballast Description The FAN7380 is a monolithic half-bridge gate driver IC for MOSFETs and IGBTs, which operate up to +600V. Fair- child’s high voltage process and common-mode noise can- celing 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=- 9.8V(typ.) for VBS=15V. The input logic level is compatible with standard TTL series logic gates. The internal shoot- through protection circuit provides 100nsec dead-time to prevent output switching devices from both conduction dur- ing transition periods. UVLO circuits for both channels pre- vent malfunction when VCC and VBS are lower than the specified threshold voltage. Output drivers typically source/ sink 90mA/180mA, respectively, which is suitable for the applications such as fluorescent/compact fluorescent lamp ballast applications and the systems that require low di/dt noise. 8SOIC 1 FAN7380 Half-Bridge Gate Driver (SOURCING/SINKING : 90mA/180mA) Internal Block Diagram HO LO COM VCC HIN LIN 5 6 7 VS VB DELAY LEVEL SHIFTER NOISE CANCELLER 1 4 2 8 3 PULSE GENERATION R S R Q UVLO UVLO LOW-SIDE DRIVER HIGH-SIDE DRIVER |
