As demand for higher power density and efficiency continue to increase, PMIC - Motor Drivers, Controllers (PMIC-MDCs) play an important role in the power conversion process. TC648BEOA is an integrated low-voltage power driver with advanced functions, minimizing the negative effects of cross-conduction and minimizing supply current inrush when operating in DC voltage. This article will discuss the application fields and working principle of TC648BEOA.

Application Fields of TC648BEOA

The application fields of TC648BEOA include motor-driven applications, such as actuator and robot drives. As a low-voltage power driver, it targets applications where high efficiency and low power losses are necessary. Additionally, its complexity allows for the switching of loads at various swapping rates while providing a high degree of protection, including short-circuit protection and over-temperature protection.

The TC648BEOA utilizes an optimized single-switch architecture, thereby achieving high efficiency, which helps reduce heat dissipation, extend product lifetime and reduce system cost. Additionally, due to the current sensing and fault protection features, it is ideal for applications that require a backup power source or for multi-phase switching.

Working Principle of TC648BEOA

The TC648BEOA incorporates the reverse current detection circuit, over-temperature protection circuit, zero voltage switching signal controller, DAC filter and other integrated functions. Based on the state signal input, it implements zero-voltage/transition switching of the external MOSFETs. During normal operation, the driver accelerates both MOSFETs, driving them towards the on-level, then latches and maintains them in the on-state.

When the switch pin voltage is below the off-level, the driver current quickly decreases to the gate-emission current, causing the MOSFETs to turn off. Moreover, after the current is lower than the off-level, the drive begins to reset, thereby reducing reverse-current vias MOSFET.

The TC648BEOA driver features a wide operating voltage range from 7 to 30V, allowing it to be used in a variety of applications. In addition, it provides an externally adjustable over-temperature protection circuit and a shutdown signal port for input, which can be used, for example, to signal the unit to shut down during brownout conditions. Due to these features, The TC648BEOA can provide enhanced overall performance and reliability for a variety of motor-driver applications.
