PMIC - Gate Drivers
The TPIC44H01DA is a monolithic and highly integrated power management integrated circuit (PMIC) designed to providing high-speed design, low RDS(on) FETs control, and reliable gate drive for high-efficiency, high current and high frequency applications. It is designed to increase the efficiency and accuracy of gate drive, by providing the optimal drive current and voltage level for high-frequency switching applications. This device can drive mosfets directly with low power losses through the switch, and thus it is an essential part of the power management subsystem in end equipment applications such as servers, consumer electronics and automotive.
Application Fields
The TPIC44H01DA is a high-efficiency and low-RDS(on) device specifically designed to help meet the efficiency requirements of audio amplifiers, high power ratings, high frequency requirements and other amplifier applications. The device has four independent low side gates to control four high side MOSFETs, with each MOSFET having its own dedicated control input. TPIC44H01DA is used to reduce the voltage drop of the power MOSFETs, minimize power consumption and minimize operating current consumption. It also helps to reduce heat dissipation in the system and improve the noise immunity of the system. Other applications include power inverters, power supplies and other active rectifiers, allowing for a low on-state voltage drop and improved efficiency.
Working Principle
The TPIC44H01DA combines the excellent high efficiency, low RDS (on), low power loss, and high current control features to meet the stringent performance requirements of high power rating and efficiency applications. The integrated device has four independent low side drive outputs with individual control input and can drive both logic-level and high-side MOSFETs. On the low side, the device funds a special buffeting technique to reduce dv/dt noise created by the load current on the MOSFETs. The built-in under voltage lockout (UVLO) circuit helps to prevent accidental turn-on of the MOSFETs and an internal temperature monitor helps ensure safe operation. The internal short-circuit protection circuit also prevents a sudden rise in Vgs if a short circuit occurs.
Conclusion
The TPIC44H01DA is an innovative power management integrated circuit (PMIC) designed specifically for providing high-speed, low RDS(on) FETs control, and reliable gate drive for high-efficiency, high current and high frequency applications. Through its self-driven and low-power design, the device increases the efficiency and accuracy of gate drive, reduces heat dissipation and improves noise immunity. Thanks to its excellent features and stable performance, the device is ideal for use in audio amplifiers, high-frequency power supplies, power inverters and other active rectifiers.
