Overview
| Topology | Buck Converter |
| Input voltage | 340 V |
| IC revision | A |
Description
750 W (~1 horsepower) 3-phase inverter using BridgeSwitch-2 (BRD2469W) and LinkSwitch-TN2 (LNK3205D) in field-oriented control (FOC) operation
Features
BridgeSwitch-2 high-voltage half-bridge motor driver
- Integrated 600 V FREDFETs with ultra-soft, fast recovery diodes
- No heat sink
- High-side and low-side cycle-by-cycle current limit
- Optional latching low-side current limit
- Configurable latching or hysteretic over-temperature protection
- High-voltage bus monitor for overvoltage protection (OVP)
- Error flagging through the Error Flag (EF) pin or FAULT bus on the MCU interface
- Supports any microcontroller (MCU) for sensorless field-oriented control (FOC) through thesignal interface
- Instantaneous phase current output through the IPH pin of each BridgeSwitch-2 device
- +3.3 V supply available through the interface
Typical applications
- High-Voltage Brushless DC (BLDC) Motor Drive
