The LM2104 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 IN pin allows the device to be used in single PWM input applications, and the SD pin allows the controller to disable the driver’s outputs by turning them off when the SD pin is low, regardless of the IN pin state.
The fixed dead-time and 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 LM2104 is 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.
