The IRL8113 is a high efficiency, low on-resistance, full-bridge MOSFET driver. It provides a highly efficient interface for driving large N-channel MOSFETs, making it the ideal choice for many switching power applications, from general purpose drive tasks to high-end applications.

The IRL8113 is a full-bridge MOSFET driver specifically designed to drive four N-channel MOSFETs. It integrates four high-current half-bridge drivers and four low-resistance full-bridge drivers, allowing users to drive high-current, high-frequency switches with low loss. The driver provides a wide range of features that simplify MOSFET drive and control, including built-in bootstrap circuitry, synchronous rectifier support, dead time control, and protection features.

The IRL8113 features a high-current, high-side driver with an adjustable on-resistance of up to 1.5 milliohms, enabling low-loss switched current of up to 80 A. A separate 12 V logic supply allows control of the MOSFETs from one supply , as opposed to conventional drivers that require two separate supplies. The device also has a wide operating voltage range of 7-24 V and a integrated low-side driver, enabling a single-supply bridge configuration up to 24 V when coupled with one N-channel MOSFET.

The core of the driver is a full-bridge-driver IC, with four independent MOSFET drivers and four integrated MOSFETs. The four integrated MOSFETs are part of the full-bridge configuration, allowing the driver to handle currents up to 80 A peak. The half-bridge driver provides a maximum peak current of 10 A per channel, while the full-bridge driver provides a maximum peak current of 30 A per channel.

The IRL8113 has advanced protection features to ensure safe operation of the device. The driver is protected from overcurrents and over-temperatures, eliminating potential for excessive drive current or thermal runaway. The device also features fault detection and protection, allowing the user to detect shorts or other faults before they cause damage.

The IRL8113 is the ideal component for high-efficiency, high-seed, high-current motor and power supply applications. The device can be used to drive large power MOSFETs with low loss, while eliminating the need for additional control circuitry and components. The integrated protection features ensure safe operation, while the integrated low-side MOSFET driver allows a single-supply bridge configuration. With its advanced features, the IRL8113 is the ideal choice for demanding motor and power supply applications.
