What are the key features of DRV8323?
- 65 V rated 3-phase gate driver with programmable 1 A to 2.5 A source/sink gate current supports a wide range of MOSFET sizes for motors from 10 W to 2 kW
- 3 integrated current shunt amplifiers with selectable gain (5×, 10×, 20×, 40×) eliminate discrete op-amps and reduce BOM cost in FOC motor drive designs
- SPI or hardware interface configures dead time, gate drive strength, and fault reporting, enabling rapid design iteration for brushless DC and PMSM motor control
What is DRV8323 used for?
DRV8323 is designed for brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) drives in e-bikes, drones, power tools, and industrial servo systems operating up to 65 V. Its integrated current sense amplifiers and programmable gate drive make it ideal for field-oriented control (FOC) implementations paired with microcontrollers or DSPs requiring precise phase current feedback.

Frequently Asked Questions
For a 48 V BLDC motor drive, how does DRV8323's gate drive current setting affect switching losses and MOSFET selection?
At 48 V bus voltage, DRV8323 can be configured for 1 A to 2.5 A gate drive current via SPI registers. Higher gate current charges the MOSFET gate capacitance faster, reducing switching transition times from 100 ns to under 40 ns and cutting switching losses in large-die MOSFETs, enabling efficiency above 95% at full load in motor drives up to 500 W.
How do the integrated current shunt amplifiers in DRV8323 simplify a field-oriented control (FOC) design?
DRV8323 includes 3 current shunt amplifiers with selectable gains of 5×, 10×, 20×, or 40× that directly measure phase current through low-value shunt resistors, typically 1 mΩ to 10 mΩ. This eliminates 3 discrete op-amps and associated passive networks from the PCB, saving up to 20 components and shrinking the analog front-end area by approximately 30% in a typical FOC implementation.
What fault protection features does DRV8323 provide for motor drive designs in harsh industrial environments?
DRV8323 integrates overcurrent protection, MOSFET short-circuit detection, undervoltage lockout at 6 V, and overtemperature shutdown reporting via a dedicated FAULT pin. Each fault condition is individually readable through the SPI status registers, allowing the host MCU to distinguish between gate drive faults, overcurrent events, and thermal shutdowns without additional discrete protection circuitry.
