IR22141SSPBF is a high-side and low-side power MOSFET driver device that is able to control up to 1.5A peak load current for either high-side or low-side applications. It is a full-featured device providing logic level inputs, low resistance outputs, and high switching speed performance. IR22141SSPBF is designed to drive the power MOSFETs (PMOS) and N-channel MOSFETs (NMOS) to realize a smart power switch interface which is essential for managing the power system, protecting the MOSFETs, and optimizing the efficiency in the system.

IR22141SSPBF mainly used in the field of PMIC - Gate Drivers. It has dual low-side and high-side gate driver over-current protection, a latch immune protection, and two enable inputs. The device also offers a wide operating range, the input voltage range is from 3V to 5.5V and the load voltage range is from -40V to +40V. Furthermore, its enable threshold under-voltage lockout (UVLO) features prevent the device from being enabled at a voltage lower than the specified threshold. All these features improve the robustness of the system and ensures reliable operation at low power consumption.

IR22141SSPBF applies to standalone, isolated and non-isolated Gate driver applications. Depending on the application, these can be used to safely drive large loads such as motors, relays, LED dimming duties, or high current switches. Additionally, the device integrates a dynamic pull down circuit into its internal structure which allows it to detect a short circuit and act accordingly.

The working principle of IR22141SSPBF is straightforward. It functions as a dual low-side and high-side gate driver, allowing the user to control the power MOSFETs from a logic source through its low level inputs. The device provides over-current protection for both high-side and low-side applications, preventing over-current conditions from causing catastrophic failure. Furthermore, the enable input Threshold Under-voltage Lockout (UVLO) ensures that the signal won’t be enabled at a voltage lower than the specified threshold. When operating, it is also able to detect short circuit conditions and react accordingly by pulling down the gate signal.

Overall, IR22141SSPBF is an optimal power MOSFET driver designed specifically for PMIC - Gate Drivers applications. Featuring logic level inputs, over-current protection, low resistance outputs, wide operating range, and enable Threshold Under-voltage Lockout (UVLO), IR22141SSPBF minimizes power losses, optimizes efficiency, and improves system robustness and reliability. All these features make IR22141SSPBF a wise choice for demanding applications, for it enables the low-power and optimized design of power systems.
