The floating high-side driver is capable of operating with supply voltages up to 100V. LM5100/LM5101 High Voltage High Side and (LM5100) or TTL input thresholds (LM5101). An integrated high voltage diode is provided to charge the high side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing clean level transitions from the control logic to the high side gate driver. Under-voltage lockout is provided on both the low LM5100/LM5101 High Voltage High Side and Low Side Check for Samples:LM5100, LM5101 1FEATURES PACKAGE 2• Drives Both a High Side and Low Side N-• SOIC-8 Channel MOSFET • WSON-10(4 mm x 4 mm) • Independent High and Low Driver Logic Inputs (TTL for LM5101 or CMOS for LM5100) DESCRIPTION • Bootstrap Supply Voltage Range up to 118V The LM5100/LM5101 High Voltage Gate Drivers are LM5100A/LM5101A 3.0 Amp High Voltage High Side
