Summary: High-voltage gate driver for driving high-side and low-side n-channel mosfets.
The Texas Instruments LM2101 Half-Bridge Gate Driver is a compact, high-voltage gate driver designed to drive high-side and low-side n-channel MOSFETs in synchronous buck or half-bridge configurations. -1V DC and -19.5V transient negative voltage handling on the SH pin improves system robustness in high-noise applications. The small, thermally enhanced 8-pin WSON package improves PCB layout by allowing the driver to be closer to the motor phases. The Texas Instruments LM2101 is also available in an 8-pin SOIC package that is pin-compatible with industry standards. Both the low-side and high-side power rails are equipped with undervoltage lockout (UVLO) for protection during power on and off.
