The IRS2308STRPBF is a gate driver for power management integrated circuits (PMICs). In PMIC applications, it is used to drive the gate of a power MOSFET or IGBT switch. The device is a monolithic half-bridge solution built on a photolithographic process. It offers a fast, efficient, and safe way to drive highly reflective power MOSFETs or IGBTs used in various applications.

To help ensure fast and reliable switching, the IRS2308STRPBF includes a fast and precise over-current protection (OCP) circuit to protect against excessive loading. This circuit activates under low pulse currents and provides an adjustable time delay before disengaging. This feature preserves the switch and prevents damage to the end system.

In addition to its over-current protection (OCP) circuit, the IRS2308STRPBF includes a pre-drivers circuit to ensure fast and reliable switching of the power device. This circuit is adjustable from 4.5V to 20V and provides a suitable non-inverting drive for driving the power device in applications where the gate capacitance is high. The pre-drivers circuit also provides an adjustable differential turn-off current, allowing for flexibility and design optimization.

Furthermore, the IRS2308STRPBF features a high-side driver to support fast, safe and efficient operation of power MOSFETs or IGBTs in high-side switch applications. This driver operates over a wide supply voltage range from 4.5V to 20V, providing robust performance and high efficiency. This driver also maintains a stable voltage level on the switch gate to ensure reliable switching and prevent damage to the power device.

Finally, the IRS2308STRPBF includes a slew-rate control circuit to control the input slew-rate and reduce the risk of noise and transients. This circuit provides adjustable slew-rate control with a minimum of 10 mV/ns and a maximum of 20 mV/ns. This ensures consistent and reliable switching performance with minimal overshoot.

The IRS2308STRPBF is easy to use and designed for applications in industrial, automotive and consumer electronic markets. It is available in 4x4x0.9mm and 5x5x0.8mm packages, making it ideal for space-constrained applications. The device features a supply voltage of 4.5V to 20V, a working temperature range from -40C to 125C, and a maximum operating frequency of 2MHz.

The IRS2308STRPBF is a versatile and reliable gate driver for PMICs. It provides protection against overloading and ensures fast and efficient switching. Its adjustable pre-drivers circuit, high-side driver and slew-rate control circuit provide robust performance and high efficiency in various applications. With its small package size, wide operating range and low power consumption, it is ideal for space-constrained applications.
