eBike and Industrial Motor Control with MC34937 Driver - Demo
特性
- Extended supply voltage operating range: 6.0 to 58 V
- Wide dead time range (50 ns to 12 μs) programmable via the SPI port
- External FET gate drive capability of >1.0 A with protection
- Charge pump ensures sufficient external FET drive at low supply voltages
- Device protection against reverse charge-injection from CGD and CGS of external FETS
- Integrated overcurrent, desaturation, and phase fault-detection
- Immunity against positive or negative transient voltage spikes on the gate driver
- Current shoot-through protection built into dead time control
- Supports direct 3.3 V and 5.0 V logic interface to MCUs
- Integrated current sensing amplifier
- Device configuration and diagnostics through the SPI
