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.
