Non-Isolated Gate Drivers

The BD2270HFV is a charge pump gate driver used together with an N-channel MOSFET to switch a load on and off. It will typically provide 12 V of gate drive and VCC can range from 2.7 to 5.5 V. The BS2101F, BS2103F, and BS2114F are dual (high and low side) gate drivers which can drive IGBTs or MOSFETs. The high side supports operation up to 600 V; it includes an undervoltage lockout for both channels and accepts logic inputs of either 3.3 V or 5 V. Recommended VCC is 10 to 18 V. The BS2103F and BS2114F also include dead-time generators which prevent current shoot-through. The BS2114F also has a high-current output stage which can source and sink 500 mA.
