FAN7380
Features
Half-Bridge Gate Driver (SOURCING/SINKING : 90mA/180mA)
Description
The FAN7380 is a monolithic half-bridge gate driver IC for 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=9.8V(typ.) for VBS=15V. The input logic level is compatible with standard TTL series logic gates. The internal shootthrough protection circuit provides 100nsec dead-time to prevent output switching devices from both conduction during transition periods. UVLO circuits for both channels prevent 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 * 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
