IR2214SSTRPBF is an integrated advanced gate driver IC rated for 400- volts maximal peak voltage and 87-volt minimal peak voltage. This chip is commonly used for power stage design for several applications and technological advancements. IR2214SSTRPBF belongs to the family of gate driver Power Management ICs (PMICs). Gate driver PMICs are special class of integrated circuits with the primary function of providing control signals to switching devices. These control signals allow enhancement of the power control over the switching devices, enabling higher performance and other increased features. The IR2214SSTRPBF is a two-channel gate driver capable of driving two independent High-Side and Low-Side external power MOSFETs in both common source and source follower configurations. It is an ideal device when needing to control N-channel power MOSFETs or IGBTs used in various motor-drive applications such as air-conditioners, washing machines, refrigerators, and other home appliances. In addition, IR2214SSTRPBF is also suitable for a wide array of motor-control solutions, including appliances as well as industrial automation. The IR2214SSTRPBF’s 8-pin, low-noise design allows for a smaller size than other traditional designs with improved noise performance and reduced overall component count. The device’s power supply voltage range is from 7-V to 22-V and can achieve a peak output current as high as 1.7 A in low side and 3.7 A in high side. It also has an internal level-shift rate of 1.2 V. The primary features of IR2214SSTRPBF includes two independent and synchronized drivers for high-side and low-side N-channel power MOSFETs or IGBTs, thermal shutdown protection with auto-restart functionality, adjustable dead time, adjustable slew rate, and adjustable under voltage lockout. These features make IR2214SSTRPBF an ideal solution for a wide range of motor control applications as its very low on-resistance reduces switching losses and its high current capability enables fast switching. The adjustable slew rate and dead time also helps to onboard users to adjust the overall performance to their desired level.The IR2214SSTRPBF’s main working principle is based on its two independent drivers that activate and drive the external power MOSFETs or IGBTs. The high-side and low-side drivers are supplied with an adjustable reference input signal. The signal then goes through the internal level-shift to generate the appropriate voltage level required to control the N-channel power MOSFETs or IGBTs. The two independent output signals are generated by the two drivers and are synchronised so they can be activated simultaneously or separately. The adjustable Under Voltage Lockout can be used to protect the system from lower input voltage and the Thermal Shutdown prevents possible overheating due to too high a load. In case of an extreme overload, the device will shut down both the high-side and low-side outputs to protect the entire system.In conclusion, IR2214SSTRPBF is a very capable and reliable device for controlling N-channel power MOSFETs and IGBTs, making it a great choice to power different applications, ranging from home appliances to industrial automation. Its main features enable increased performance anywhere and its very low on-resistance reduces related losses even further. These factors, combined with the adjustable slew rate and dead time, make the IR2214SSTRPBF the ideal integrated device when seeking improved power control and enhanced performance.
