IR21834PBF: PMIC Gate Drivers The IR21834PBF is a part of the Power Management Integrated Circuit (PMIC) family, particularly the Gate Drivers category. PMICs are essential parts that enable and control different electrical systems. They save energy, increase efficiency and reduce risks of destruction. This article seeks to provide an overview of the IR21834PBF, and one’s knowledge of the company and its PMIC gate driver series.Overview The IR21834PBF is a gate driver integrated circuit that incorporates advanced BiCMOS FET (Bipolar Complementary Metal Oxide Semiconductor Field Effect Transistor) technology with high efficiency and low power. The unit is part of the MOSFET (Metal Oxide Semiconductor Field Effect Transistor) series of devices and is optimized for low gate charge and low gate resistance. It can be used to drive low to medium gate power MOSFETs and is capable of controlling gate voltage from 0V to +5V. This product has a small footprint and is capable of carrying up to twelve channels for control of gate voltages.Application FieldThe IR21834PBF can be used in a variety of applications, including in motor control and power systems. It is optimized for driving motors and other applications such as LED lighting, battery management, power conditioning and AC-DC/DC-DC conversion. It can also be used in AC/DCSMPSs (Switched Mode Power Supply), induction cookers, HVAC (Heating, Ventilation and Air Conditioning) systems, computers, medical equipment and other applications. Working PrincipleThe IR21834PBFis typically used in conjunction with an onboard controller, such as a microcontroller. The microcontroller establishes the logic for the circuit and reads commands from an external source. Upon receiving a signal from the external source, the microcontroller will decide to either connect or disconnect the output from the circuit.The basic working principle of this device is to drive the gate of a MOSFET in order to control whether or not the voltage/current passes through it. In general, the IR21834PBF works by allowing the gate voltage to go from 0V to +5V. This allows it to control the gating current when operating at low to medium power levels. Finally, the device offers superior current and thermal characteristics, making it suitable to drive both high-voltage and low-voltage MOSFETs. It is also designed to be able to directly interface signals with a low-level logic, such as TTL or CMOS. ConclusionIn conclusion, the IR21834PBF is a part of the PMIC family, particularly the Gate Driver category. This PMIC gate driver has a small footprint and is designed to deliver superior current and thermal characteristics. This makes it suitable to operate at low to medium power levels and to handle both low-voltage and high-voltage MOSFETs. It can be used in a variety of applications, including motor control and power systems, LED lighting, battery management, power conditioning and AC-DC/DC-DC conversion. It can also be used in AC/DCSMPSs, induction cookers, HVAC systems, computers, medical equipment and other applications.
