THS6043IDR

The THS6043IDR is an integrated gated driver that is focused in the voltage domain rather than current, which is the norm for many other devices. It is designed to drive a wide variety of loads, including p-channel and n-channel MOSFETs. The device can provide up to 3A peak current, and features wide input and output voltage ranges, programmable fixed output voltages, 1MHz or 15MHz operating frequencies, and adjustable current limit.

Application Fields

The THS6043IDR is ideal for a wide variety of applications, including LED lighting, power MOSFET switch mode converters, booster converters, and motor control. Its features make it suitable for applications where high peak current is required, as well as those requiring fast switching speeds and accurate voltage regulation. It is also highly reliable and efficient, making it ideal for applications where power savings are a factor.

Working Principle

The THS6043IDR operates by controlling the amount of output current passing through its internal MOSFET switch. When the input voltage is above the threshold voltage, the MOSFET is turned on, allowing current to pass through it. The current then passes through another MOSFET switch, which is connected in series with the load, and is controlled by the output voltage. When the input voltage drops below a certain value, the MOSFET is switched off, preventing current from flowing. This allows the output voltage to remain constant even if the input voltage varies, so that the load is not damaged.

The device features adjustable over-current protection, adjustable slew rate, and adjustable over-temperature protection. The integrated current limit also helps to protect against damage caused by over-current. It is designed to be used as part of a control system which also includes sensors, comparators, and other components. This system is then used to regulate the output of the device, guaranteeing a safe and efficient operation.
