IR21844STRPBF Typical application Circuitry

IR21844STRPBF

The IR21844STRPBF is a distinguished half-bridge driver from the IR's (International Rectifier) renowned gate driver IC portfolio. Designed with cutting-edge HVIC (High Voltage Integrated Circuit) and latch immune CMOS technologies, the IR21844STRPBF is specifically crafted to manage both N-channel power MOSFETs and IGBTs in a range of configurations, with an emphasis on half-bridge topologies. As such, assimilating a detailed approach to embed the IR21844STRPBF within electronic systems, extending down to the individual pin levels, is crucial to tap into its full potential.

1. VCC: Catering as the logic power supply terminal, VCC is where a positive voltage (commonly between 10-20V) is introduced, powering the IC's internal operations.

2. LIN & HIN: Respectively signifying 'Logic Input for the Low Side Gate Driver' and 'Logic Input for the High Side Gate Driver', these pins accept PWM signals to steer the corresponding MOSFET or IGBT.

3. HO & LO: While 'HO' directs the gate drive output towards the high-side MOSFET or IGBT, 'LO' focuses on its low-side counterpart.

4. VSS: This anchor pin establishes the logic ground, interfacing with the system's common ground.

5. VB: A bootstrap-based high-side floating supply terminal, VB needs connection to an external capacitor that collaborates with the VS pin to provision the drive voltage for the high-side device.

6. VS: Complementing VB, this terminal connects both to the source of the high-side device and the negative facet of the bootstrap capacitor.

7. SD (Shutdown): This pin facilitates an external shutdown signal. Introducing a logic 'low' safely turns off both high and low side outputs.

8. VREF: This output offers a reference voltage, commonly utilized for protection circuits or other ancillary features.

9. COM: Serving as a reference ground, this pin is the common point for input and fault signaling.

10. ITRIP: An input for over-current shutdown, this pin, when used, ensures protection against excessive current scenarios.

11. CSH & CSL: These pins, respectively, monitor the high-side and low-side MOSFET or IGBT current via external shunt resistors.

12. Additional Integration Insights:

- Bootstrap Configuration: Leverage an external diode and capacitor to create the bootstrap reservoir for the high-side driver. This entails linking the diode's anode to VCC, its cathode to VB, and positioning the capacitor between VB and VS.

- Stabilization: Introducing a ceramic capacitor between VCC and VSS, preferably in close proximity to the IR21844STRPBF, aids in stability and noise mitigation.

13. Operational Precautions: Ensure synchronization of input signals to LIN and HIN to preclude 'shoot-through' or simultaneous conduction of both half-bridge components. Always operate within the specified voltage range on VCC as recommended in the IR21844STRPBF datasheet.
