MP1906 10-16V Gate Driver SOIC

MP1906 10-16V Gate Driver SOIC

The MP1906 is a high-performance, 80V, gate driver that can drive two external N-MOSFETs in a half-bridge configuration with a 12V gate supply.

Typical Application Circuit

Applications

• Motor Drivers
• Half-Bridge Power Supplies
• Avionics DC-DC Converters

Design Notes

• The current-limit threshold must stay inside the SOA of the pass device at the applied voltage, including startup inrush.
• Hot-swap inrush control is set by the slew rate on the gate or the dV/dt capacitor — too fast trips the upstream supply.
• Reverse-current blocking behaviour differs between ideal-diode and load-switch topologies; pick the one that matches the fault you are protecting against.
• Route the fault flag to a pin the firmware actually polls; a latch-off protection with no report looks like a dead board in the field.
