LM5109
100V/ 1A Peak Half Bridge Gate Driver
General DescriptionThe LM5109isa low cost high voltage gate driver, designed drive both the high side and the low side N-Channel
MOSFETsina synchronous buckora half bridge configura-
tion. The floating high-side driveris capableof working with
rail voltagesupto 100V. The outputs are independently
controlled with TTL compatible input thresholds.A robust
level shifter technology operatesat high speed while con-
suming low power and providing clean level transitions from
the control input logicto the high side gate driver. Under-
voltage lockoutis providedon boththe low side andthe high
side power rails. The deviceis availablein the SOIC-8 and
the thermally enhanced LLP-8 packages.
Features Drives botha high side and low side N-Channel
MOSFET 1A peak output current (1.0A sink/ 1.0A source) Independent TTL compatible inputs Bootstrap supply voltageto 118V DC Fast propagation times (27ns typical) Drives 1000pF load with 15ns rise andfall times Excellent propagation delay matching(2ns typical) Supplyrail under-voltage lockout Low power consumption Pin compatible with ISL6700
Typical Applications Current Fed push-pull converters Half and Full Bridge power converters Solid state motor drives Two switch forward power converters
