Instructions for Using the IR2110S
Power Supply Connections:
- Connect VCC1 to the high-side supply voltage, typically between 10V and 60V.
- Connect VCC2 to the low-side supply voltage, typically between 10V and 25V.
- Ensure that the supply voltages are within the specified range to avoid damage.
Gate Drive Outputs:
- The high-side gate drive output (HO) should be connected to the gate of the high-side MOSFET or IGBT.
- The low-side gate drive output (LO) should be connected to the gate of the low-side MOSFET or IGBT.
- Use appropriate gate resistors to control the switching speed and reduce ringing.
Input Signals:
- Apply the input signals (IN) to control the high-side and low-side outputs.
- The input signals should be TTL/CMOS compatible with logic levels of 0V (LOW) and VCC2 (HIGH).
Bootstrap Capacitor:
- For high-side operation, a bootstrap capacitor (CBOOT) is required to maintain the high-side gate drive voltage.
- Connect one end of CBOOT to the HO pin and the other end to the VS pin.
- Choose a capacitor value based on the switching frequency and load conditions to ensure sufficient charge during each switching cycle.
Under-Voltage Lockout (UVLO):
- The device has built-in UVLO to protect against insufficient supply voltage.
- If VCC1 or VCC2 drops below the UVLO threshold (8.5V), the outputs will be disabled.
- Ensure that the supply voltages are stable and above the UVLO thresholds to prevent unintended shutdowns.
Thermal Management:
- The maximum operating junction temperature is 150°C.
- Use a heat sink if necessary to keep the device within its thermal limits, especially under high power conditions.
Layout Considerations:
- Keep the gate drive traces as short as possible to minimize parasitic inductance and improve performance.
- Place decoupling capacitors close to the VCC1 and VCC2 pins to filter out noise and provide stable power.
By following these instructions, you can ensure reliable and efficient operation of the IR2110S in your application.
