The LM5101BMAX gate driver provides high efficiency powering of the gate of an external MOSFET, thereby allowing the external MOSFET to switch faster and consume less power. The LM5101BMAX is designed for use with N-channel MOSFETs and diodes, but can also be used with other high voltage devices such as IGBTs, power BJTs, power MOSFETs, and power diodes. The LM5101BMAX gate driver features a low on-resistance, high-side MOSFET switch and a high frequency, low on-resistance, low-side MOSFET switch.

The LM5101BMAX has an adjustable dead time control, which allows for setting the on and off state timing of the low and high-side MOSFETs. The dead time control can be adjusted from 0 ns up to 200 ns, allowing for fine-tuning of the output waveforms to meet power converter design objectives. The maximum dead time must be limited so that it is not greater than the minimum on-time of the external MOSFET.

The LM5101BMAX can also be configured as a two-phase synchronous buck converter, allowing for low output ripple, high transient response, and improved efficiency. The LM5101BMAX can also be used to drive any synchronous buck converter topology. It supports both fixed and adjustable voltage applications. The LM5101BMAX has a low input voltage range of 0.5 V to 10 V and an adjustable output voltage range from 0.5 V to 10 V.

The LM5101BMAX gate driver can be used for a variety of power management applications, including motor control, power conversion, lighting, motor drives, and power sequencing. It is ideal for use in automotive, medical, industrial, and consumer applications. The LM5101BMAX gate driver can also be used as a switchmode controller in power converters, providing fast response, fast turn on/off, and excellent power efficiency.

The LM5101BMAX gate driver features multiple protection functions such as over-current fault chronic and thermal protection. Its integrated current sense terminal allows direct sensing of the current of the external MOSFET. The LM5101BMAX also incorporates an automatic shutdown feature, which can be enabled to automatically reduce the current through the external MOSFET in the event of an over-current fault. It also features a high accuracy Current Limit Comparator (CLC) which monitors the peak current during switching cycles.

The LM5101BMAX gate driver is an advanced power management solution that delivers high efficiency and low on-resistance switching. It has a wide input voltage range with adjustable dead time control and low on-resistance low side MOSFETs. The LM5101BMAX gate driver is designed for applications requiring high peak current drive and high efficiency. It is ideal for applications requiring fast turn on/off and good efficiency.
