ISL6700

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.
