LM5100/LM5101
High Voltage High Side and Low Side Gate Driver
General DescriptionThe LM5100/LM5101 High Voltage Gate Drivers are de-
signedto drive both the high side and the low side
N-Channel MOSFETsina synchronous buckora half bridge
configuration. The floating high-side driveris capableof
operating with supply voltagesupto 100V. The outputs are
independently controlled with CMOS input thresholds
(LM5100)or TTL input thresholds (LM5101).An integrated
high voltage diodeis providedto chargethe high side gate
drive bootstrap capacitor.A robust level shifter operatesat
high speed while consuming low power and providing clean
level transitions from the control logicto the high side gate
driver. Under-voltage lockoutis providedon both the low
side andthe high side power rails. This deviceis availablein
the standard SOIC-8pin and the LLP-10pin packages.
Features Drives botha high side and low side N-Channel
MOSFET Independent high and low driver logic inputs (TTLfor
LM5101or CMOSfor LM5100) Bootstrap supply voltage rangeupto 118V DC Fast propagation times (25ns typical) Drives 1000pF load with15ns rise andfall times Excellent propagation delay matching(3ns typical) Supplyrail under-voltage lockouts Low power consumption Pin compatible with HIP2100/HIP2101
Typical Applications Current Fed push-pull converters Half and Full Bridge power converters Synchronous buck converters Two switch forward power converters Forward with Active Clamp converters
