LM5106MM/NOPB is a high-voltage half-bridge gate driver integrated circuit (IC) designed to drive both high-side and low-side N-Channel MOSFETs in a synchronous buck or boost topology. It is manufactured by Texas Instruments. This IC is widely used in various applications like industrial automation, motor control, power supplies, and solar inverters.
LM5106MM/NOPB offers several key features that make it a popular choice among engineers. Firstly, it can operate from a wide input voltage range, from 5V to 100V, allowing flexibility in different system designs. Secondly, it supports high peak output currents of up to 4A, enabling it to drive large power MOSFETs efficiently. The high peak current capability minimizes switching losses and improves overall system efficiency.
Furthermore, this IC incorporates adaptive shoot-through protection to prevent simultaneous conduction of the high-side and low-side MOSFETs, reducing the risk of short circuits. It also offers programmable dead-time control, which adjusts the dead time between the high-side and low-side MOSFET transitions, optimizing efficiency and minimizing switching losses.
Another key feature is its integrated bootstrap diode, which simplifies the high-side gate drive circuitry. This eliminates the need for an external diode and reduces the component count and system cost
