LM5105SD Description

Short technical summary and product information.

The LM5105SD from Texas Instruments is a high-voltage gate driver specifically designed to drive both the high-side and low-side N-channel MOSFETs in a synchronous half-bridge configuration. This device offers a robust solution for power management applications requiring efficient switching.

 

Key electrical specifications include a bootstrap supply voltage of up to 118V DC and an input supply voltage range of 8V to 14V. It delivers a peak output current of 1.8A, with rise and fall times of 15ns, enabling fast switching performance. The driver features an undervoltage lockout typically at 8V and a quiescent current of 0.01mA.

 

The LM5105SD operates across a wide temperature range of -40°C to 125°C. It is housed in a thermally enhanced 10-pin WSON (4mm x 4mm) package, suitable for surface mount applications. The driver configuration is dual, single, with N-channel MOSFET gate type and non-inverting input type.
