ISL6700

80V/1.25A Peak High-Frequency Half Bridge Driver with TTL Logic Inputs

Product Status: Mass Production

OVERVIEW

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.
