Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construc- tion. The logic input is compatible with standard CMOS or LSTTL outputs, down to 3.3 V. The protec- tion circuity detects over-current in the driven power transistor and terminates the gate drive voltage. An open drain FAULT signal is provided to indicate that an over-current shutdown has occurred. The output Product Summary V CC V B CS HO V S COM IN FAULT V CC IN FAULT V CC V B CS HO V S COM IN FAULT V CC IN FAULT (Refer to Lead Assignments for correct pin configuration). These diagrams show electrical connections only. Please refer to our Application Notes and DesignTips for proper circuit board layout. driver features a high pulse current buffer stage designed for minimum cross-conduction. The floating chan- nel can be used to drive an N-channel power MOSFET or IGBT in the high-side or low-side configuration which operates up to 600 V. • RoHS compliant |
