The LM5109A is a bottom-side gate driver that is an integral part of several Texas Instruments (TI) power management integrated circuit (PMIC) products. It is designed to provide a high-voltage, high-speed, high-power-delivery gating interface between one or two power sources which can range from low-voltage supplies, such as 6V, to high-voltage supplies up to 20V. In this article, we\'ll take a look at the application field, working principle and some features of this unique device.Application Field of LM5109A
The LM5109A is available in a wide variety of PMIC products from TI, enabling the efficient power distribution from multiple power sources. It allows designers to integrate an efficient, cost-effective power supply solution for their applications. Depending on the specific product, some of the primary applications of the LM5109A include automotive, industrial, and portable computer and communication products. The LM5109A provides a reliable and easy-to-use device for designers to integrate a power management IC solution into their design. The LM5109A is also used in power supplies, distributed power, shared power, IGBT, MOSFET, MOSFET bridge, LED backlighting, and fan control applications. Additionally, it is also used in solar panel applications.Working Principle of LM5109A
The LM5109A is a driver designed to drive a voltage signal through two galvanically isolated gates, one low side and one high side. On the low side is the \'High Level\' signal, and on the high side is the \'Low Level\' signal. The signal is inverted from low to high and vice versa by the circuit.In terms of power delivery, the LM5109A achieves a wide variety of control options. For example, it can be used for PWM modulation or pulse-width modulation. It also offers overvoltage protection and slew rate control for optimal output performance.When the LM5109A is used in a buck or boost converter application, it offers various features including soft start, fast frequency detection, over voltage protection, and over temperature protection. With these features, the LM5109A is an extremely efficient and dependable solution for managing the power supply of a device.Features of LM5109A
The LM5109A comes with a few key features, including:- Output current: 220mA
- Voltage rating: 20V
- Fault detection: Over-temperature, over-current, over-voltage, cross-conduction and under-voltage
- SO-8 package
- Operating temperature range: -40°C to 150°C
- PWM or pulse width modulation (PWM) functionality
- Platform compatibility: PIC32, PIC24, ARM, ATMEL
