IRS21850SPBF

IRS21850SPBF gate drivers are widely used in many PMIC (Power Management Integrated Circuit) applications. They are designed to drive the gate of an IGBT or MOSFET with low RDS(on) and high current ratings up to 4A.

The IRS21850SPBF gate driver provides an efficient and reliable solution for controlling wide-bandgap semiconductor switches such as SiC MOSFETs, IGBTs, and GaN transistors. It also provides an optimal driving capability to reduce upon switching losses as well as an adjustable slew rate.

The gate driver has very important features that make it attractive for PMIC applications: Firstly, it includes a built-in, low-voltage, high-current gate driver with a short circuit sense resistor, so that it can provide optimal driving performance for both high- and low-side IGBTs and FETS. Secondly, a fault detection circuit is included, which is integrated on-chip and prevents any high fault current in the event of an overvoltage condition.

Further, the IRS21850SPBF includes a temperature sensor, so that it can measure the temperature at the gate driver. This temperature measurement is then used to implement a protection mechanism in the event of thermal overload. Finally, the gate driver also provides programmable slew rate and dead-time, allowing it to control the switching speed and reduce switching losses.

In practical PMIC applications, the IRS21850SPBF gate driver can be used to drive a wide range of wide-bandgap semiconductor switches, including SiC MOSFETs, IGBTs, and GaN transistors. It provides an efficient and reliable solution for controlling these switches, particularly for high-current applications, where it helps to reduce switching losses. Furthermore, the fault detection circuit, temperature sensor, and programmable features of the driver make it an ideal choice for use in PMIC applications.
