100V / 1.4 Peak Half Bridge Gate Driver
LM5107
100V/ 1.4A Peak Half Bridge Gate Driver
General DescriptionThe LM5107isa 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.An inte-
gratedon chip high voltage diodeis providedto charge the
high side gate drive bootstrap capacitor.Arobust level shifter
technology operatesat high speed while consuming low
power and providing clean level transitions from the control
input logictothe high side gate driver. Under-voltage lockout providedon both the low side and the high side power
rails. The deviceis availableinthe SOIC-8 andthe thermally
enhanced LLP-8 packages.
Features Drives botha high side and low side N-Channel
MOSFET High peak output current (1.4A sink/ 1.3A source) Independent TTL compatible inputs Integrated bootstrap diode 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
