80V/1.25A Peak, Medium Frequency, Low
Cost, Half-Bridge Driver
The ISL6700 is an 80V/1.25A peak, medium frequency, low
cost, half-bridge driver IC available in 8-lead SOIC and
12-lead QFN plastic packages. The low-side and high-side
gate drivers are independently controlled and matched to
25ns. This gives the user maximum flexibility in dead-time
selection and driver protocol. Undervoltage protection on
both the low-side and high-side supplies force the outputs
low. Non-latching, level-shift translation is used to control the
upper drive circuit. Unlike some competitors, the high-side
output returns to its correct state after a momentary
undervoltage of the high-side supply.

NOTE: Intersil Pb-free 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.
