DRV8317
Overview
DRV8317 provides three integrated MOSFET halfbridges for driving three-phase brushless DC (BLDC) motors with 5-V, 9-V, 12-V, or 18-V DC rails or 2s to 4s batteries. The device provides integrated threephase current sensing which eliminates the need for external sense resistors.
- Three-phase BLDC motor driver - Configurable slew rate for EMI mitigation - Programmable gain current sensing - Supports up to 200-kHz PWM frequency - Integrated shoot through protection
- 4.5-V to 20-V operating voltage - 24-V absolute maximum voltage
- High output current capability - 5-A peak current drive
- Low on-state resistance MOSFETs - RDS(ON) (HS + LS) at TA = 25°C : 130-mΩ (typical)
- Ultra-low Q-current sleep mode - 3-µA (max.) at VVM = 12-V, TA = 25°C
- Multiple control interface options - 6x PWM control interface - 3x PWM control interface
- Integrated current sensing - No external current sense resistor required - Three-phase current sense outputs
- SPI and hardware device variants - 10-MHz SPI interface variant for flexibility - Pin configurable variant for simplicity
