Overview
The BRD2261C-TL is a half-bridge motor driver from the BridgeSwitch-2 series by Power Integrations. It integrates two high-voltage N-channel power FREDFETs with low and high-side drivers in an inSOP-24C package. The device operates on 3.3 V or 5 V supply voltages and delivers an output current of 1.7 A. It functions within a temperature range of -40°C to +150°C. The component features three outputs and includes internal fault protection such as cycle-by-cycle current limit and thermal overload protection.
Feature Summary
- Integrates two high-voltage N-channel power FREDFETs with self-supplied low and high-side drivers
- Provides instantaneous phase current output signal for sensorless control implementation
- Includes internal fault protection with cycle-by-cycle current limit and two-level thermal overload protection
- Features external system monitoring including DC bus sensing and status reporting via single-wire interface
Applications
- Single-phase PM motor drives
- Multi-phase BLDC motor drives
- Hard switched inverter drives
Procurement Notes
Verify the specific suffix TL indicates reel packaging when sourcing. Confirm RoHS compliance details through official documentation. Ensure the inSOP-24C package dimensions match your PCB layout requirements. Check humidity sensitivity handling instructions prior to assembly. Validate that the 1.7 A output current meets your application's peak demand specifications.
Selection Notes
Select this component for designs requiring integrated high-voltage switching without external auxiliary power supplies. The self-powered driver capability simplifies circuit topology. Consider the extended operating temperature range for harsh environments. The compact footprint allows for efficient heat sinking through the PCB. Evaluate the built-in monitoring features against your system's diagnostic needs.
Part Context
This part belongs to the BridgeSwitch-2 family, which simplifies high-voltage inverter development. The series combines power switches and drivers in small-outline packages. It targets applications needing reliable motor control with reduced component count. The design eliminates the need for separate gate drive circuits.
Replacement Considerations
Consult official substitution lists for compatible BridgeSwitch variants. Verify pinout compatibility before replacing with other models in the series. Ensure voltage and current ratings meet or exceed original specifications.
