LM5110-1MX

The LM5110-1MX is a single-phase, gate-driving, pulse width modulation (PWM) power stage controller. It offers full-featured functional and protection capabilities for today’s high-current PWM power stages. The LM5110-1MX, which is part of the broad range of PWM gate drivers from Texas Instruments, provides a highly integrated solution with numerous features.

Application Field

The LM5110-1MX is suitable for a wide range of applications, including motor drives, battery-powered equipment, industrial equipment and consumer appliances. This device was designed specifically for driving high side/low side IGBTs, MOSFETs and power BJTs.

The key features of the LM5110-1MX are adjustable current limit, over-current protection, over-temperature protection, ultra-low quiescent current, short-circuit protection, adjustable PWM dead time and fast response to current limit.

The LM5110-1MX also features an adjustable dead time that helps protect against shoot-through. This eliminates the need for external solution components and provides a simple, compact and cost-effective solution.

Working Principle

The LM5110-1MX is a single-phase, gate-driving, PWM power stage controller. It has two outputs, an H-bridge and a Low side driver. The LM5110-1MX is capable of driving power MOSFETs, IGBTs, MOSFETs, or BJTs. The PWM controller provides adjustable current limit and over-temperature protection.

The over-temperature protection feature activates when the die temperature reaches a critical level. The current limit feature ensures that the device is protected in the event of a short circuit. The PWM controller has a fast response to current limit, with a settling time of less than one microsecond.

The LM5110-1MX also features an adjustable dead time to ensure that no power is conducted between the high side and low side drivers when the high side MOSFET is in active mode. This helps prevent shoot-through and leakage current when the high side and low side FETs are on. The dead time can be adjusted from 0-300ns to accommodate various applications.

The LM5110-1MX also provides ultra-low quiescent current when not in operation. This allows for improved efficiency and battery life in battery powered applications. It also features user-programmable current limit, over-current protection, output overload protection and short-circuit protection.

Conclusion

The LM5110-1MX is a versatile PWM gate driver that is suitable for a wide range of high current applications. It offers a high degree of integration and features adjustable current limit, over-temperature protection, ultra-low quiescent current, adjustable PWM dead time and fast response to current limit.

The LM5110-1MX also offers adjustable dead time, which eliminates the need for external solution components and provides a simple and cost-effective solution. This device provides a high level of protection, allowing for reliable and safe operation.
