Introduction

The TPIC46L01DBRG4 is a integrated gate driver for Permanent Magnetic Synchronous Motors (PMSM). It is an advanced power management integrated circuit (PMIC) with a rich feature set and wide operational range. The IC provides an integrated power solution for driving power switches such as MOSFETs and IGBTs in PMSM. The device’s package size is 3x2mm and only requires an input voltage of 6V.

Application Field

The TPIC46L01DBRG4 is specifically designed for Permanent Magnet Synchronous Motor (PMSM) applications. This includes applications such as brushless machineries, electric motors, power converters, AC/DC motor control, and robotics.

Since the power switch needs to be driven by an appropriate gate driver, the TPIC46L01DBRG4 serves this purpose by providing efficient and fast switching while maintaining a low-power consumption. Its features such as fast rise/fall time, high voltage ratings, and high-side/low-side Boolean control make it perfectly suitable for PMSM applications.

Working Principle

The TPIC46L01DBRG4 Integrated Gate Driver has a dual-channel switch mode drive which allows it to drive both low-side and high-side MOSFET or IGBTs. It has a central controller which is operated with a logic-level signal and can be used for the bi-directional control of current flow.

The gate driver operates with a high-precision Programmable Over-Current Protection (POCP) module and an internal feed-forward/adaptive pre-charging sequence to optimize motor performance. The TPIC46L01DBRG4 provides a fast switching time with a lower power consumption.

The device’s Low-Side Sense (LSS) allows the end user to include the sensing of the FET current in order to accurately measure the current. The motor speed is then controlled via a PWM signal and is used to determine the rate of change in the current.

Conclusion

The TPIC46L01DBRG4 is a high performance, low-power integrated gate driver for permanent magnet synchronous motor applications. It is ideal for applications such as brushless, electric motor, power converters, AC/DC motor control, and robotics. The IC also provides a fast switching time with a lower power consumption and Programmable Over-Current Protection (POCP) module and internal feed-forward/adaptive pre-charging sequence that optimize motor performance.
