IR25603STRPBF is a type of gate drivers which belongs to Positive-Drive low side drivers. It is designed tofor use in the automotive industry and other environments, where electrical connectivity and efficiency under extreme conditions is highly important. This positive-drive P-channel power MOSFET driver is specially designed to reduce the load losses of power MOSFET switching on the power grids and has a high-efficiency power supply design. In addition, there is built-in protection against current over heat, overvoltage and short circuit, and a thermal shutdown feature. Working Principle The IR25603STRPBF is generally used for low-side gate driving applications where a power MOSFET is used to switch between a high and a low state on an electronic circuit. It can be used to drive an N-Channel power MOSFET. When the gate driver is activated the P-channel MOSFET acts as a low side switch and connects the load to a low voltage source. The MOSFET operates as an open switch when no gate voltage is applied to the gate. When a driving voltage of 12V or greater is applied to the gate the P-channel MOSFET will conduct current and switch the load to a high voltage source. The IR25603STRPBF operates on a low voltage rail of 3.3V and requires a current limit of 6A which complies with the standard JEDEC specification. The gate driver features an advanced 9-bit logic and provides a buffer that is capable of driving up to 15V on the gate terminal. The gate driver contains internal circuits to protect the load from potential overvoltage and short-circuit conditions. The device also includes an advanced high-frequency power MOSFET driver for high efficiency of the switching operation.
