The LM2005 is a compact, high-voltage gate driver designed to drive both the high-side and the low-side N-channel MOSFETs in a synchronous buck or a half-bridge configuration. The integrated bootstrap diode saves board space and reduces system cost by eliminating the need for an external discrete diode.

The –1-V DC and –19.5-V transient negative voltage handling on the SH pin improve the system robustness in high noise applications. The small, thermally-enhanced 8-pin WSON package improves PCB layout by allowing the driver to be placed closer to the motor phases. The LM2005 is also available in an 8-pin SOIC package compatible with industry standard pinouts. Undervoltage lockout (UVLO) is provided on both the low-side and the high-side power rails for protection during power up and power down.
