Introduction
The RT9629AZQW is a microcontroller-based integrated circuit (IC) designed for a wide range of gate driving applications. It contains a configurable power management IC (PMIC) and a small secondary controller to easily manage the chip\'s device manipulation and synchronization. The RT9629AZQW, with its unique features, allows for maximum flexibility in applications requiring high-frequency switching, low-noise operation, burst and clock gating, and soft start-up.
Features
- Can drive up to 256 outputs in a single IC
- 3 selectable adjustable voltage settings for different device limitations
- Lower On-state resistance and higher current efficiency
- It has strong and fast output transistor capabilities
- Single-input control with ground-sensing output
- Internal over-voltage protection, open drain, and low-side switch control capability
- High noise immunity
- On-chip thermal protection
Applications
The RT9629AZQW is a versatile, multicontrol device. Its high-efficiency, low-noise performance makes it suitable for a wide range of applications including:
- Gate driving for MOSFETs and IGBTs in switching power supplies and solar power inverters
- High-power motor controls
- Stepping motor control
- Industrial equipment and home appliance control
- LED lighting control
- Automotive control systems
- Wireless charging systems
- Battery management systems
Working Principle
The RT9629AZQW is designed to operate with various gate-drive sources such as general purpose digital (GPD) or analog output logic, as well as external clock sources. The RT9629AZQW has an internal PMIC that provides adjustable gate-drive voltages (Vgdrv) to the output devices and can be programmed to provide one of three settings (Vref1, Vref2, or Vref3) depending on the specific operating needs.The chip\'s internal control logic is composed of PWM controller and logic gates. The logic gates are configured according to the gate-drive voltage settings. The logic gate controls the logic inputs sent to the PWM controller, which in turn generates the output PWM signal and regulates the output voltage of the gate driver.The RT9629AZQW also contains an internal noise filter to reduce ringing caused by switching between high and low output states. This noise filter reduces the likelihood of turn-on/turn-off transients and minimizes electromagnetic interference (EMI). The chip\'s level shifter circuit also allows for compatibility between different logic levels.
Conclusion
The RT9629AZQW is an advanced gate driving IC for power management and high efficiency applications. Employing advanced features such as an internal PMIC, adjustable voltages, and advanced logic gates, the RT9629AZQW delivers a high level of performance. It is suitable for a wide range of applications, including motor control, LED lighting, automotive control, and wireless charging.
