1 FAN739 High-Current, High & Low-Side, Gate-Drive IC Features Floating Channels for Bootstrap Operation to +6V Typically 4.5A/4.5A Sourcing/Sinking Current Driving Capability Common-Mode dv/dt Noise Canceling Circuit Built-in Under-Voltage Lockout for Both Channels Matched Propagation Delay for Both Channels Logic (S ) and Power (COM) Ground +/- 7V Offset 3.3V and 5V Input Logic Compatible Output In-phase with Input Applications PDP Sustain Driver HID Lamp Ballast SMPS Motor Driver Description July 212 The FAN739 is a monolithic high- and low-side gatedrive IC, which can drive high speed MOSFETs and IGBTs that operate up to +6V. 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 =-9.8V (typical) for V BS =15V. The UV circuit prevents malfunction when V DD and V BS are lower than the specified threshold voltage. The high current and low output voltage drop feature make this device suitable for the PDP sustain pulse driver, motor driver, switching power supply, and highpower DC-DC converter applications. 8-SOP 14-SOP Ordering Information Part Number Package Operating Temperature Range Packing Method FAN739MX 8-SOP Tape & Reel -4 C ~ 125 C FAN739M1X 14-SOP Tape & Reel FAN739 Rev. 1..6
