Half-Bridge Drivers
Features
• Drives N-Channel MOSFET Half-Bridge
• SOIC and DFN Package Options
The ISL2110, ISL2111 are 100V, high frequency, half-bridge
N-channel power MOSFET driver ICs. They are based on
the popular HIP2100, HIP2101 half-bridge drivers, but offer
several performance improvements. Peak output pull-up/
pull-down current has been increased to 3A/4A, which
significantly reduces switching power losses and eliminates
the need for external totem-pole buffers in many
• SOIC and DFN Packages Compliant with 100V Conductor
Spacing Guidelines per IPC-2221
• Pb-Free Plus Anneal Available (RoHS Compliant)
• Bootstrap Supply Max Voltage to 114VDC
• On-Chip 1Ω Bootstrap Diode

range has been extended to 8VDC. The ISL2110 has
additional input hysteresis for superior operation in noisy
environments and the inputs of the ISL2111, like those of the
• Fast Propagation Times for Multi-MHz Circuits
• Drives 1nF Load with Typical Rise/Fall Times of 9ns/7.5ns
• CMOS Compatible Input Thresholds (ISL2110)
• 3.3V/TTL Compatible Input Thresholds (ISL2111)
• Independent Inputs Provide Flexibility

1. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations.
Intersil Pb-free products are MSL classified at Pb-free peak
reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
Applications
• Telecom Half-Bridge DC/DC Converters
• Telecom Full-Bridge DC/DC Converters
• Two-Switch Forward Converters
• Active-Clamp Forward Converters
• Class-D Audio Amplifiers
2. Add “-T” suffix for Tape and Reel packing option.
